Fixing An Antique Chainsaw. Stihl 028 Wood Boss.

I tear into this old chainsaw to fix it, and it has a few surprises in store for me. It didn't occur to me when I was working on it, but this saw is an antique at 43 years old. This turned out to be an enjoyable but tricky repair!

[@FarmCraft101]

Yep, this was a tricky one, which for me makes it more enjoyable in the end. Though it did take me awhile, I'd take this over just rebuilding the carb any day. Ignition tester: amzn.to/48SdqEG. Electronic ignition module: amzn.to/3v3pNQo. Have an awesome weekend everybody!

[@breikowski]

Curious if original carb ran the saw after ignition repair?

[@Melicoy]

I only watch for the seals

[@cristianstoica4544]

I've had many years ago (~2000) a similar problem with a 79 Ford Taunus (German made) carburetor that would not start the car in cold even if you asked it nicely... After a fewf clean-ups and some repair kits I ended up putting a flange and a carburetor for a different car with similar size engine. Went to a dealer, changed some jets and they tuned it and worked like I a charm. It still bugs me to this day what I didn't know that could help me fix it.... After a few years I drove the car for the last time. I've noticed that the car run perfectly and my father noticed this as well... It was a bitter sweet moment. That was the car I put my most work into and thought me a few things about rust and what one can fix and when one should let go.

I have an Old 41 Farm Boss I'd like to have rebuilt that's about 45 or 50 years old. Is something you can successfully work on?

[@DennisFahlstrom]

Jon, if you were not a teacher in your previous worklife, you really missed your calling. I learn more from your informative and well presented podcasts than I did in most of my high school and college classes. Your tenacity is amazing, your videos are technically superb and your presentations are well paced and mixed with a nice blend of humor. I hope you keep up the great work for many years to come and I wish more presenters on KZbin could take lessons from you. 👍👍👍

[@erik_dk842]

The kind of teacher we all wish we'd had

[@mattym8]

Agreed.

[@pierreparraud]

wonderfull explanations, I have the same saw, and have the same problem, thought it was chock issue, and now I believe I need to check the spark, great thanks.

[@user-qe2kj8kj7r]

Truth!

[@jswjr6001]

The learning model....rote memorization, understanding, application, and correlation.... Memorization is useless for this, but understanding the functionality, applying the concepts, and correlating the lessons learned to future problems is great. And to integrate those while working through "failures" is where he shines.

[@Travawing]

I bought my Stihl 028 Wood Boss in 1987 to clear off an area for our new house. It has always been a great saw. After watching your video, I discovered the manual says it has an electronic ignition, so that should be good. Over the years though, I have rebuilt the carburetor with new kits and never had real good luck with them. In the end, I replaced the whole carburetor with a cheap China one from Amazon and it has worked like new ever since! It is the only chainsaw I have ever owned and definitely don't consider it an antique!

[@markkaminski2416]

I bought mine in 1986 and use it regularly. I burn 4-5 cords per year. Along with an 036 they run great and still going strong.

[@saxus]

That grinder on the lathe... It's both hilarious and genius.

[@DB-yj3qc]

As soon as I seen the grain grinder on the wood lathe I started to laugh.

[@robertdavis6708]

Sounds like it's crank seals John. Put a cap on the exhaust and pump it up. If it leaks, pull the engine apart and reseal it. A couple of hours will make a dandy saw.

[@Mikeygm]

John Do a leak down test on that motor to make sure you do not have crank case leak. The 028 is known for bad crank seals/ impulse line/ intake manifold boot. Also the coil you bought is a electronic ignition coil. Just hook the kill switch to it and it will work. Do away with electronic ignition module if you want to put that new coil in that saw.

[@michiel1362]

Well that is some incrowd knowledge, really nice

[@georgemartinezjr]

That was I thinking Leak test it. Lots of hard issue come from Leak test

[@paulmaxwell8851]

Thank you for these tips! I'm never too old to learn new things.

[@jaguar3552]

This is what I love about old mechanical tools, they're fixable! I like the electric stuff but man when they fail, they're not easily repairable and I guarantee they won't be lasting 40 years like this saw!

[@watcherofwatchers]

I haven't found too many modern tools that can't be repaired; they just need different skills and sometimes a creative method of sourcing parts.

[@jaguar3552]

@@watcherofwatchers that’s a good point and great perspective. I’ve soldered connectors back to Bluetooth speakers and resisters back to boards but the new tools seem so cheaply made, sometimes it’s better to replace than to fix. Love the content on this channel, though. Fixing things and bringing life back to stuff is cool regardless of what it is.

[@jerryb953]

I bought this exact saw around1980. I have cut many cords of wood with it since then and it is still going strong. One of my favorite saws and I have several. This was considered to be a PRO saw by old timey repair guys as it was manufactured before STIHL started making three levels of quality. I refuse to look at it as an antique cause then I must be old {77}.

[@blenderheadxyz2418]

[@jerryjohnson3047]

I have an old 028 myself. Watching I was having flashbacks from about 7 years ago. I pulled points out and added module. starts everytime and runs great. One of my favorite mid range saws

[@upperpine]

I have a Stihl 028AV that I bought new around 1984 but have not used it for a decade after moving to a bigger saw. My wife says I have too many saws so have been working on it to get it running to sell. I feel like I'm watching myself while viewing your video so I'm taking the electronic step...that's all I have left for options. LOL. Thank you very much for the video. Excellent narrative and editing.

That was an invaluable invite into chainsaw repair , I have experienced all of thease symptoms in the past, I will now use your method to diagnose and repair , thank you for sharing your knowledge and time

[@andyfields3248]

The high speed jet should be adjusted at wide open on the trigger while under load in a cut. This is why saw shops used to have a big hardwood log out back before government took away the adjustment screws. There are screwdrivers that lock onto the jet to make this easier. Same thing, find where it starts stumbling in both directions and put it in the middle. You'll be amazed how much more power you can dial in.

[@Brian-wy7ts]

Turning the high screw on full throttle with no load until rpm is the highest then backing it off until it '4 stroke's also works

[@phillipdean9879]

Great video John, very enjoyable. Small engines can be very temperamental hey! 🇦🇺🍺🍺

[@stefantrethan]

The official Stihl way is to adjust no-load RPM at full throttle (with an electronic RPM meter), but I also usually use your method.

[@thess518]

100% wrong. There is a spec in every Stihl Tech Manual for a top no load speed setting. The high is adjusted 500rpm under that spec for a saw that is broken in and 1000 for a brand new saw. It should be adjusted using a digital tachometer.

[@newrenewableenergycontrol5724]

Love your videos! My Daddy taught me something very valuable for memorization in these situations. "I'm not a fig plucker, I'm a fig pluckers son, but I'll pluck figs til the fig plucker comes!" When you encounter a troublesome machine like this, repeat this phrase three times. Things will become crystal clear!

[@zorrosoxter4703]

I rebuilt my Dads old 041 from 1978. You would be amazed at the amount of parts Stihl still has kicking around for factory parts including carb rebuild kits, bearings, etc. I did have to go aftermarket for some stuff, but I expected as much. The saw runs pretty well now.

[@scottpecora371]

I still own an 028 that my father bought when I was 15 y/o. I'm now 61! Still a damn good saw, which I've cut a lot of winter firewood with. Never have torn it down. I've just serviced it over the years, and replaced the bar once

[@scapriglione8642]

This was one of your best videos. You covered all of the “mysteries” of small engine repair that we all can use to better diagnose and fix a variety of issues. I feel much more confident tackling problems that arise with these engines now. Makes me want to revisit an issue I’ve been having with my tiller! Many thanks to you Jon!!

[@DannyCreech]

Jon, good job on your stick to it mentality. When I was having a problem with my Stihl bogging down I talked to my Factory Stihl Repairman and he told me to only run 92 octane fuel with the 2 stroke oil in it. If you can get it without Ethanol it is even better. I changed the 89 octane fuel to the 92 and wow, that really fixed my bogging down. I am sure you already know it but this was news to me and I thought I would share it with you. Great video. Oh and the flower grinder was priceless. You think a lot like me. hahaha

[@aaronconner2010]

I love the little details of these small combustion engines. Thank goodness for brilliant engineers and inventors that came before us!

Agreed, that's my main saw and I got it as a wedding gift brand new from my father-in-law.

[@AnomadAlaska]

My first saw was from that vintage. I got it well used in the early 90's while attending college and still have it. It is a Stihl 009L and thank dog the chain oiler still works.

[@ZakPeirce]

I got that exact same saw from my dad too! Mine runs like a top, just had to give the carb a good run through. It’s a workhorse and does an awesome job. Thanks for showing me the air filter splits apart, I had no idea.

[@jcondon1]

Two strokes with multiple issues can be a real challenge to sort out. It sounded great in the end. Always worth the effort to save a Stihl saw.

[@superjojo555]

good to see u here lol

[@jcondon1]

I am working on 2 Stihl 028 AV SUPER chainsaws right now. Both belong to a subscriber. One he has owned since new and has sentimental value to him. It ran great until he let a friend borrow it. He straight gased it and burned it up. Well build saws, definitely worth saving.

[@johnsmith-xr6qy]

Our .o32 takes two pulls with choke on, fires, chole off & it's ready to crank and cut wood. It was this way when new and today about 15 years old. Stihl is hard to beat. I am amazed at your patience and the few bleeps necessary to complete a project. Good info & video.

[@twrcha]

Great video, thanks grand master chief for the depth of your knowledge and unlimited set of skills.

[@critical-thought]

I absolutely LOVE your grain mill drive! Creative solution. As for the saw, your methodical approach to fixing it may have taken a little longer, but you know everything else is good. Ditching the mechanical points is something I may not ever have thought of. Really appreciate what you do and share with is all. THANK YOU!

[@patrickd9551]

I have replaced the mechanical ignition on both of my Suzuki cars. And I instantly gotten stronger spark and like 5HP extra instantly. (which is a lot in a car with only 50 factory HP to begin with)

[@keitho77]

Oh that special, fuzzy feeling when you diagnose and fix something that's broken 👍 How addictive!!

[@erikcourtney1834]

First thing I do with a non running saw is check compression with a tester. If someone puts the wrong gas or mixture in (it happens a lot) or another issue leads people to turning jets….. making a lean mixture. Both will burn up the piston and cylinder very quickly. With a saw that runs but not great, pull off the muffler and look into the cylinder. Then rotate the engine slowly and look at the piston. Exhaust side is the one that gets burned up from excessive heat. Just a small amount of scoring will drop compressing causing it to run or start poorly.

[@terriblet4145]

Wow, thanks for reviving the old 028 Wood Boss. I purchased mine in 1984 and ran it hard for 30 plus years before giving it to my younger brother. It still lives on at the farm cutting fire wood. Brother tells me it runs better than his 2 newer 025's. Besides chanes, bars, drive sprockets, spark plugs and some other small maintenance items, still starts on the 3rd pull after sitting for a week and 1 pull after running and shut off for a break. Dont make them like they used to.

[@mattshell7753]

I have 1 just like it I'm so blessed It was my father's now mine Never been in the shop yet When I need to if anyone can ever fix it I love my saw. Thank you thank you for the video.

[@talesfromthebottle6314]

My old 038 magnum is by far my favourite saw. Takes a minute to warm up but once it does it'll run all day

[@gregorythomas333]

I ordered both PC-7 & PC-11 as I needed some good epoxy and this stuff seems really good.

[@franciscocerutimahn]

I also have them and they are great, BUT they are slow to cure (hours). If you need something fixed quick, get JB Weld KwikWeld or similar.

[@merlepatterson]

I had a Stihl 051 with a 36 inch bar from the same era as your 028. Thing was a beast.

[@johnhuntley3006]

Weak spark always shows up when the throttle is opened because the compression is much higher than at idle. It is much harder for the spark to jump at higher compression. Adjust high speed jet under load. Will get rid of bog down while cutting. Nice video John. Thanks

[@TheMadJoker87]

man, i love these videos, i never would have guessed there were points under that flywheel, always learning something new

[@shadovanish7435]

Great diagnosis video for the old Stihl chainsaw! I would not have guessed that a chainsaw made in 1981 would still have had non solid-state (points & condenser) ignition, & since electronic ignition is usually very reliable (& durable), I didn't suspect bad ignition as a likely cause of the engine's non acceleration issue (I imagined the issue was almost certainly carburetor related). When you decided to replace the condenser with an electronic ignition module, I thought that theoretically (& ideally), that should be a big improvement (over points & condenser ignition), but practically, I thought the fit & quality of the aftermarket electronic ignition module might be questionable, & so I thought it might have been better to obtain Stihl OEM replacement points & condenser (to insure proper fit & quality). After all your diagnosis, I'm sure you would have wanted to determine the cause of the engine's non acceleration issue, without additional uncertainies of replacement part quality (such as the new aftermarket coil, which was bad "right out of the box). Regardless of the aftermarket electronic ignition module issues, I think you did a thorough & meticulous job fitting all the ignition module parts & wiring, & did great work overall! The old chainsaw sound great!

I inherited this exact model of chainsaw from my father which he bought in the late 70's or early 80s. It runs great. Always starts on the third pull even after no use for over a year. But once it gets warm after about 5 minutes of use, it sounds just like your saw. I think I'll try this ignition module and see if that does the trick. Thanks for the video, its such a great resource when I go to do work on my saw.

Have one since new! 1990. Only thing I’ve done is new carb from the Hipa Store and new plug probably 3 years ago. Runs like it did new. Cold starts on third pull, first pull when warmed up. A little heavy for a 47cc saw with 16” bar, but all metal! 👍🏻 Thanks for the video!

[@Treeoflifewoodworks]

I decided to try it out and after putting new gas in it, it fired up on the 9th pull. I put a knew plug in it and it starts on the second pull every time. I cut several loads of firewood with it and I love it!

[@bobkelly2447]

LOL.... I walked out just before you found the points the last time I watched this, watching it again and I was thinking I bet theirs points in that thing ! and sure enough... the way it was running just pointed to me the points/condenser the condenser in particular in this case ...my hats off to you as I bought one of those little electronic ignition module a long time ago and I fought it for a week trying to get the thing to work and finally gave up and put the points back in it ! (on an old B&S 3.5 hp).... I never seen any of those things work ! I've had friends tell me nah they are junk, they don't work ! yet You got one to work WOW ! I've had several saws with points in fact I think I still have 2 ! it would have been really interesting to see if just replacing the condenser cured the problem.... but I guess we'll never know now !

My 028 starts and runs whenever I need it. Its amazing. I've had it 15 years or more and maybe changed the plug. Chickanic recently did a video on how to flex the diaphram to get it working - once its running.

[@memylastname9972]

Great video! I have several saws and the latest addition is a 051 AV electronic. The spark died and the it’s the old Bosch module they fitted instead of points. I am hoping one of these aftermarket modules will work for this saw too. It’s amazing that they get the timing right.

[@douglasthompson2740]

Fuel lines are replacement items. Over time the rubber disintegrates causing cracks and leaks. When you needed a clamp on the fuel line it indicates that it was on the way out if not gone. At that time it makes sense to change the pickup line as well. Change the in tank filter as well.

I sure enjoyed this. The one minor detail, but could be major is: (has nothing to do with fixing the saw) when actually cutting with the saw, ALWAYS wrap your thumb around the saw handle when cutting. This gives you much more stability if and when there is kickback or any other unexpected movement of the saw. This may not be “textbook”, but it was what I was taught. Thanks for your videos!

[@rickmartinson5252]

John, I own a Stihl 028-WB similar to the one you repaired. I believe I purchased it in the mid 1980's My saw has always been a difficult starter but once I pour a little fuel in the spark plug chamber it takes right off. Switching to Tru-Fuel has made a big difference in starting and I no longer need to pour fuel in the cylinder. I always clean the saw and dump the fuel after use. Your tutorial is timely as I need to do my annual maintenance on my saw. Great videos as always.

[@noahlechner1036]

Another great video, just one thing I wanted to let you know. The gas can you used to fill up your saws actually had an auto stop with a check ball so you actually can’t over fill it as long as the nozzle is in the tank

Dude I just looove your narration and story telling process. Such a pleasure to watch.

[@twwtb]

I have had very good service from the 20V Dewalt electric chainsaw. It routinely bites off and chews a lot more than I thought it could. Even though I would say that it is really just a limbing or pruning saw, I have made some very big cuts with it. And no small engine temperament to deal with. Just charge a battery and pull the trigger. Though, it is entertaining to watch you trying to get that thing to run right.

[@prevost8686]

I purchased my 036 new in 1994. We heated with wood exclusively for 10 years and every bit of it was cut with it. When we purchased 20 acres of wooded land it’s bee used constantly to keep the land cleared of damaged trees. It’s never had ethanol blended gas in it and it’s ran on Amsoil Sabre oil exclusively. If I went out to the barn right now it’d start on the third or fourth pull. I’ve put numerous bars, chains, gas filters and clutch sprockets on it but the engine remains untouched. Stihl built a great saw back then.

[@jeffs8812]

I rebuilt the same saw just over a year ago, it had a cracked piston. Stihl wanted unbelievable $ for a piston and rings but found them on Amazingzon for under $30. Just like your saw it was my fathers saw and I used it as a early teen up till i left the house. It then sat from sometime shortly after 1986 when it quit until late 2022. I don't use it much as I have several newer saws but I pull it out to use occasionally to use on 12"-14" diameter and smaller trees or limbs. It was mated with a 20" bar and chain but I use a 16" on it now. They were a super popular back in the day and were really stout for their era. Great content and I really enjoy all your videos.

[@anthonyhoult152]

[@MRrwmac]

Several great points forus to have learned from! Thanks Jon!

[@fredwilson7732]

The spark strength required to jump the gap increases when the plug is in the cylinder and under compression. It takes more voltage to jump the gap due to the higher air density. But, fuel will conduct electricity so that helps get the spark across the gap. A low compression rich mixture takes much less voltage that a high compression lean mixture. That "S" on the spark test tool is the minimum spark length required in free air to get a consistent spark in a cylinder.

[@richardthompson924]

Hi John really love your vids. Had same issue with my Stihl blower . Bought a chinesium carb no problems since 😊

[@colinsigley5771]

An excellent video. I have nearly finished servicing my Stihl machines. One thing that I have found out over the years. Replacing carburettors rather than trying to repair them is much more effective in terms of both cost and time. Incidentally, Stihl carburettors are branded Stihl but made in China.

Thanks for the video John… I have one of these (maybe two?? 🤔) and it is doing exactly the same thing as yours. I put in a carb kit and it bogs down under throttle. Now I know where to look. I never would have expected these to have a set of points. Love the channel… love the videos… keep up the great work! 😃👍🏻

John (Jon SP?) that was awesome! I learned more about small 2-cycles in this one video than I have in ten years of fighting with them! I was watching intently to the end for the punchline, because those were exactly the symptoms I experienced with my first chainsaw, an old Homelite that someone had donated to the family. I tried *everything*, up to the ignition testing and replacement that you did, and with exactly the same lack of results. After a couple of years of using the POS to cut firewood, my mom back in California shipped me a new 14" Echo for my birthday, which probably saved me from death via head trauma from beating it against a brick wall. The worthless Homelite got stuck away in the water heater closet while that Echo blew my mind with the differences! Now for my own punchline... That paperweight sat until, on some whim, I went looking for it and discovered it'd been stolen by a certain tweaker . Here's to getting one's just desserts when he tried to trade it off for dope!

I have a old 028 Super and went through about the same issues last year. After some TLC it runs beautifully and has plenty of power. I bought it used and not running. The few dollars spent was well worthwhile.

Best grain mill I've seen. 😊😊

Great video. A few years ago I dismantled an 026 that belonged to my grandfather. It must also be from the 80s, it hadn't been running for 20 years and it had ignition problems. I think I have the same problem.
