How to tune a chainsaw carburetor!!

[@Mornin-Wood]

I'm glad I started watching some of your older videos. This one is a gem for us newbies.

[@budgillett9627]

I heat with wood and everything I know about chainsaws I’ve learned on KZbin. I think I’ve watched nearly every KZbin on carb adjustments. This is hands down the best video by far! You are an excellent teacher! Thank you!

This is the exact way to tune a carb. I was taught the same way back in 1979. Been working for me since then and for my Dad decades before that. You can feel when it’s right when you’re in the cut, also the sound tells you. Great job Tinman!

Thanks Tinman. That's the best tutorial on carb tuning I've seen.

[@thoreau5914]

What a great video. I grew up with wood heat and have heated with wood primarily my entire life (70 years) and still do, so obviously I have had thousands of hours with a chainsaw in my hands. I currently have 6 or 7 saws, from 6.5 HP Neo Tec NS 8105 with 36" bar all the way down to 14" trim saws, various brands. I still learned some things here. I was having a little trouble adjusting the carb on my ECHO CS 310 yesterday and I got it running much better, but I didn't know you should adjust for when it is under load and a little blubber is good when not under load. Makes prefect sense and you demonstrated it perfectly. Liked and subscribed. Great job sir. Thank you.

[@patwilson707]

Hello tinman from Ireland, best carb tuning video to date on KZbin 👍👍

[@cormacbailey775]

Greetings from wlcklow

[@crxess]

Very much appreciated finding this video. You are the first(I have found) that actually not only explained 4-Stroking, but took the time to Present the Chainsaw under the condition. I've become comfortable with Tweaking the Carburetors on my saws to find good response and decent top RPM - and I always back off a little to avoid Lean running, but I never knew the saw would tell me where it is happiest. My tweaking experience comes from mostly picking up used Saws Cheap, that almost always have fuel line/Carburetor issues. I have found, as I purchase new (Less Expensive) Chainsaws that they almost always need Adjustment after a break-in period to get better overall performance. The knowledge you share makes things much easier to understand and correct! Thank you!

[@darrenpierce9903]

Fantastic commentary. Great vids. Just getting into porting and your videos have helped a lot. Many thanks , Darren from New Zealand

this video is without a doubt the best carb tuning vid out there easy to understand special note to anyone reading this comment the instructions on adj high jet till it 4 strokes when pulled out of cut is key here thats what i could never get right until now so now im not afraid of making it to lean thank you very much great vid

[@kotystrelow5436]

Thanks Tinman! This is the clearest and easiest way I've seen to tune a saw.

[@byrontjrcooley1857]

Timing I have started working on 2 strokes bout 4 years ago after I had a stroke and couldn't keep up the pace in a large autobody shop . I have listened to all the big saw guys out there bout carb tuning, Iron horse,Bellhopper,Buckin Billy Ray, Steve's Saloon, Fleet Command. It has never been simplified and step by step as you have explained it so thoroughly as you have. I've just started to get into the porting stages of my career and I'm so glad I ran across your channel. I will be enjoying your videos and your library for a long time. This is Byron and I thank you.

[@TheScoundrel70]

Rewatching this one again for the 5th or 6th time, the explanation and demonstration is excellent, particularly when you realize this was an opportunistic, off-the-cuff video Tinman shot while out sawing rather than a planned video with all the equipment and done in the shop. Why am I watching this again? I was trying to sort out my neighbor's early Husqvarna 55 yesterday evening for him. Someone had truly buggered up just about everything you could do to the saw, then "gifted" it to him when it was so out of tune, it wouldn't even start. So after stripping it down, cleaning it all out, testing for spark, fixing the spectacularly buggered chain brake, greasing the needle bearings, bar, etc. we finally put it back together, dropped some fuel in it, and got it to run. I went though all the steps I had written down (so I don't go cowboy on it myself), and the saw just ran beautifully. I was a bit suspicious on the idle setting since it took a total of 4 turns to get it to slow down to where the chain wasn't trying to engage, and it idled smoothly for 4 minutes, but woke right up at the touch of the throttle. I even got it to do the 4-stroke out of the wood (tach was reading the free speed at about 10800rpm), but clean when in the wood setting, and we sawed a few smaller white ash logs to confirm it ran consistently. BUT...we shut it off, and put it down for 3 minutes. When we went to restart it, my tack was clocking the idle speed at 4300-4400rpm, and the saw would NOT settle back down! WAY too fast. So I went back to square 1 and turned everything back in, and back out to re-establish a base starting point again. Nope, Idle on start instantly jumps to 4300-4400, and the saw will actually cut. Nothing I did made any difference except on the top end, so at 1am, we rang the bell and ended the round, calling it a night. Same thing on round 2 when I worked on it today. The plug is not looking lean at all and throttling up from the sdoopit-high idle is snappy and torquey in the wood. That sort of points me away from air leaks in my mind, but I did a check anyhow, to the best of my amateur tinkerer ability. I'm not sure what it might be or what the next step to take is (other than loaning him one of my saws until I can get this figured out). Any thoughts or suggestions would be welcome!

[@justme-ij2qy]

If it were me at this point I would check for air leaks in the filter system, a bad carburetor gasket, or cracked fuel line. Any of those can cause problems with the air fuel mixture and it can be intermittent making it tough to troubleshoot.

[@justme-ij2qy]

Now that I am further into the the video I see that he mentioned air leaks too. Lol.

[@dld4045]

Probably the best video on adjusting the carb on a chainsaw!

[@ronpatterson6420]

Excellent how to video. Altitude plays a big role too, for example I live at 2400 ft but I do most of my cutting at 6200ft so my saw runs very rich at my house but its spot on when I'm on the mountain. Thanks for making this video.

[@jeffvw1994]

Should be the opposite, the higher the elevation the leaner you need it because the air is thinner.

[@ncode03]

When I started using saws, I was used to tuning motorcycle carbs so tuned it until it had no four stroke on top because I thought it made the saw run smoother. Only recently I learnt that you need to rich it a little bit and have that four stroke so you won't burn your saws. I'm tuning it better nowadays because of videos like yours and thankfully I haven't burnt any saws all those times I did it wrongly because I never used them heavily

[@GripFreak]

Excellent instructions!!! In a nutshell your saw is better off on the rich side. Too lean equals burned up saw. Thanks for sharing your experience Tinman!

[@SNELLERIZED]

Good video. There are a couple things I'd add. The last thing you should tune is the H needle. WOT is a combination of the fuel from both the L and the H needles. What you do to the L has an affect on WOT tuning. Also, tuning is most likely to change when you re-install the filter cover. It'll probably be richer with the cover installed. The struggle is real in getting on those needles though, lol :)

[@markluxton3402]

Agree that he needed to recheck the high jet after adjusting the low, and I agree about the change after reinstalling the cover, if the cover restricts enough air flow. He probably could hear that the H was still good though. You also have a very good grasp of 2 stroke carb. adj..

[@streetbikebilly2597]

Thanks

[@Ballroomblitz255]

I'm new to chainsaws and what i like about your video is that the process is straightforward and understandable, adjusting and allowing us to hear the sounds understand what the adjustment is actually doing. I have a carb adjustment toolkit coming in and i'll give it a try and try and get things dialed in well enough. I only do a few tree's a year and low jet is likely a bit rich as it is idling a bit low with stalling at times, and some stumbling/hesitation on pulling the trigger. I'll try leaning it out (1/8 to 1/4 turn clockwise) till i find that sweet spot. Update: Tool set came in and adjusted it in just a few minutes, was the low jet (L) as i thought from watching your video. I turned the L screw all the way clockwise, then set it 1.5 turns counterclockwise open. From there toggle the screw 1/8 to 1/4 turn each direction and found 1/8 clockwise (lean) from the initial setup was perfect. Chainsaw no longer stalls or bogs down on initial trigger pull, and an added bonus it starts on second pull of the starter rope whereas prior it took 10-12 pulls and then would idle poorly and stall. Appreciate Tinman for giving me the knowledge and confidence to take on this task, saves me time and money as i don't have to take it in for adjustment and with the toolset (specialty screwdriver bits, Amazon, $24) i can adjust my chainsaw from time to time as the temperature and barometric pressure changes. My chainsaw took a PACMAN bit as like many small equipment carburetors today they do not use a standard bit to ensure people do not adjust their own equipment due to pollution mandates. So if you have a newer chainsaw you might have to purchase a 2 cycle carb adjustment tool set, Amazon is awesome for that and a 10 bit set is $24.

[@rwetmore2386]

Thanks Tinman! I was messing around with my ported 372 today and something just wasn’t right with it. Now I can at least sorta know what I’m doing and what to look for so I don’t hurt the saw! You’re awesome buddy!

Excellent and you covered all the theories perfectly. I run ALL MY SAWS a bit RICH just like you here to keep them from burning a hole in the piston. I like how you show how it works in wood and how to test your settings. I was taught by a Logger back in the '70's and I've never burned a piston and still have that first Homelite XL550 from those days and it still runs...NO SAFETY FEATURES what so ever so I don't use it but it still runs.

[@markw2266]

I'm doing crank bearings and seals on a echo cs8000 at the moment. My advice after making a mistake with a seal is to order 2 of each crank seal if your repair is time sensitive. It's so easy to mess up a seal which completely stops the build. Super easy to over drive a seal as well especially if the seal gets a little crooked at the start. Good luck!

Excellent demonstrastion! I just unboxed an Echo 7310P a couple of days ago first run yesterday on a giant red oak with very sound wood. Even with the 32" bar fully buried and aggressise chain, it 4-stroked. Echo says not to re-tune until broken in. But, next job is with somewhat smaller ash with 24" bar, it will "burble" all over the place if I do not lean it out some. It has limiters, so it may not lean out "idealy"; but like you say, a bit righ is way safer than a bit too lean.

[@johnub1143]

It's also important to have the saw warmed up fully first too.

Excellent tutorial. Used to fall trees for a living many moons ago with a Husky 480 and Husky 385 on the east foothills of the Rockies. Looks like you have a good handle on carb tuning. Couple of tidbits which I know you're aware of is a clean air filter is imperative and a broken spring in your clutch will cause the chain to run on.
