Easy to follow and thorough step by step tutorials do it yourself (DIY) to help you with your broken lawn and garden equipment including snowblowers.
I do my best to teach you how to easily diagnose problems the fastest, quickest and most efficient way with real repairs beyond just replacing a spark plug. These tips are for both the homeowner and shop owner.
Whether it be a handheld, two stroke, two cycle engine like a chainsaw, weed eater, weed wacker, string trimmer, grass trimmer, line trimmer, hedge trimmer, strimmer, brush cutter, leaf blower, or four stroke, four cycle units like a lawnmower, wood splitter, lawn tractor, snowblower, pressure washer, generator or a ride on mower that needs parts installed or replaced, I’m your go-to guy.
My favorite brands of spark plugs are NGK and Champion and are the ones I recommend.
I’ve been a small engine mechanic for many decades and also run my own repair shop so my videos are loaded with tips and tricks that I have learned and want to share with you. You will also find many tool and product reviews from top brands on my channel as well.
I have the largest Small Engine Repair Video Library on KZbin and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!

Smashing repair don :-D, that looks really strong and saved replacing the whole casing. I love the grease trap tip, small things that make smarter repairs :-D

[@donyboy73]

just pinned your comment buddy, have a good weekend!

[@dwaynemadsen964]

Oh yes! I was going to mention the grease trap idea, too! I'll just add my expression of amazement and awe under this one rather than edit my other post.

[@zed8083]

Work smarter, not harder! Great vid Don! Cheers!

[@mcarroll598]

Great video as always Dony! Just curious why you didn’t put any loctite on the Heil coil into the engine body?

[@billlovett4256]

Great question.

[@atibbs14]

How do you determine which coil to use? Would have been nice to see that.

[@gunnerneikoify]

One thing that should always be done when using helicoils is to locktite the helicoils themselves into the newly threaded/taped hole, especially in a chainsaw!!!

[@alanross3435]

You Canadians are the best!👍🏻 Another great video D! Stay safe brother!😷😷✌🏻️

[@michaelreiche2240]

Great video. I bought an MS661 that leaked oil from a bar stud and had metal shavings in the oil tank. And when I removed the bar to investigate, the bar stud came out instead of the nut. The person that did the heli-coil should have watch this video. Why blue locktite (removable) instead of red (permanent)? Also - surfaces must be clean and free from oil for maximum holding of locktite.

[@SimpleLife1971]

Another perfectly executed repair with step-by-step instructions...Outstanding Dony!

[@rabbithatethefox]

Great Video I shall know what to do if I ever come across the same problem.I have been looking for a video on tank vent and fuel tank information for stihl 038 magnum but cannot find any video nor any information elsewhere. Just wondering if you could help answer these questions.Whilst doing a vac test should the vaccum hold for a little bit then go down?also what about pressure should the fuel tank hold constant pressure? or should it hold for a little bit then slowly drop down? I have three 038 magnums One saw wont hold pressure or vacuum cannot pump it up at all. The other saw holds pressure constant and leaks down with vacuum.Then the other saw when pumped to 7psi will come down to zero in about 70seconds both on pressure and vaccum.Thanks for your videos any help much appreciated.

[@rjb6327]

Thanks for your videos. I don;t own a chain saw but the information you supply wiil come in handy if I need it on another project. Keep up the good work.

[@ОлегБ-л8м]

Great job! I have never seen anything like it. Everything is beautiful and neat - just great!

[@Hogleg1percent]

Awesome Thank you. I followed your video step by step and it worked perfectly. I love KZbin University

[@ComfyBe]

As usual another fine job Dony. On another note, considering that the saw is a rental, its ghastly looking cosmetic condition doesn't surprise me. Some folks just don't have any clue of how to take care of equipment, or just don't care. I say that because my 27 year old Stihl 025 not only works as good as the day I bought it, but it also almost looks as good.

[@bencarter2334]

You can’t beat stihl. There pro gear is as good as its ever been and their domestic stuff Is great. Just proves if you look after it it looks after you.

[@BionMTG]

Just bought a used Stihl 034 Super Magnum from a garage sale and the engine fires but the bar/chain was coming loose so I got it at a steal IMO. I plan on heading down to the local parts vendor and getting a service kit, and a couple new studs, and apparently a Heli-Coil kit. Great video and thanks for saving me some head-scratching time!

[@monkeyboy563]

And volia! another awesome "How too" video! Thank you Donyboy73!

Nice repair, too bad Princess auto or online don't have an affordable SAE Helicoil kit. I have the metric one and then a whole pile of different metric bolts to go with it.

Nice work! That stud is going nowhere!

[@Mr.Martin4500]

Great work, easy to understand methods for the DIY guy's. Could you please offer where to find the part's you are changing out? It's fairly easy, but to have a confirmation from a professional is always better for this guy. Thank you Sir

[@dwaynemadsen964]

“et voilà !” I guess Ontario is neighbors with Quebec! Thank you for sharing another very clear and instructional video! Stay safe up there!

[@mattcasdorph]

Doesn't work on Poulan. The studs appear to be made into the plastic. I love my Poulan but that is a stupid design. I dont buy overpriced shit like Stihl because I've always found I could get the job done with cheaper brands. And Im not crazy about paying high prices foe replacement parts just because of the brand name. People can make the argument that its better quality but I don't see it

[@RhinoRider2006]

Obviously Canadian. Princess, my second Home

[@Stang413]

Great video! I have never seen a thread insert like that before. It makes sense since you can’t tap the hole any larger or it will be too big for the stud.

[@antonmessner9040]

Very good explain in english also understandable for readers from Germany.. it is perfect your repoert. it to use for METAL-HOUSES, less for PLASTIC-Material.. you could another lesson for PLASTICS?? THANK YOU!!

[@mitchz.6234]

That was easy...thanks to you for all the Great tips today Don!! Keep them coming.

[@TheCrittercam001]

Don your videos are the absolute best! Always great closeups, great explanations and great instruction on the proper use of various tools. I especially love all of your chainsaw repair videos as they have assisted me on many occasions when I'm making repairs on saws. Thanks a bunch for sharing your wisdom and displaying your knowledge and skills☺♥

[@gasperajdnik5627]

Donyboy73 IS my favourite youtober 😉🤠

[@johnclarke6647]

The bar studs on the 361 are about a quarter inch shorter than they should be, which might account for the stripped bar stud. Good job.

[@barrylee.freedman2203]

Red locktite on coil insert placement, could that cause problem This is 2yrs old, curious how it’s holding up. Another UT’er have had failures opting for OEM oversized bolt. Different approaches overall like in medicine, adds art to the science. Yes I’ll smack myself for being arm chair quarterback.😊

[@patrickmoote]

My Bar Bolt just spins and wont come off. I assume the nut or bar is stripped, but I cant get the clutch cover off so its har to tell. How did you get it off??

Great video. I just stripped one of my studs today on the exact same model Stihl. I must’ve been over tightening the nuts.

[@mkilptrick]

Great video as always. Learned something new today.

[@tommie793]

I have a Stihl MS 181c? Crank case is plastic and no threads in hole. Worn out completely. Would I still need to use drill?

[@woodlandburl6648]

Nice job. Thanks.

[@37yearsofanythingisenough39]

A spiral flute tap would pull the swarf out of the hole as it was tapped. Of course that would add to the manufacture’s cost which ultimately raises the cost to the end user and you can’t just use a spiral flute tap you would be able to purchase separately as taps for helicoils cut oversized to accommodate the insert. Too bad it’s always about money.

[@rudeboz5486]

hi don could you tell me what size drill bits go with the helicoil set as i was given a set but some of the drill bits are missing ,have looked on line but can,t see any info ,great repair i,m always watching your channel on fixing things .

[@firefighter1241]

I thought Stihl cases were magnesium not aluminum?? Love that stick LOCTITE 248. Easy to apply and doesn’t drip everywhere. If not used often it will form a top crust that’s easy to pull off. I’ve use Time Certs to fit small holes on the cases and even the muffler mounting holes on a 200t with good success.

[@arnenelson4495]

Too bad scrench's don't have a built in torque limiter to assist those who have no idea how to properly tighten threaded fasteners. We all have to learn tho.

[@nathanielfisher8829]

How much time , is involved in the repair? If you were being billed.

[@famasmaster2000]

Nicely done....I always wondered how to change those if they ever broke.

[@skipproctor8979]

Great tip Don. Another reason not to junk an expensive saw like this with this problem.

[@Vickvineager]

Same thing on my end. I had an 026 with the same problem & thought I had to get a whole new crankcase, but they stopped making them in 2012 & then I happened to stumble upon this video. Saves me a lot of money & wasted time.

[@dbcriss21]

I'm about to do this repair. If you are not drilling all the way into oil tank, how are you blowing air through the oil tank.

This is good to know if I ever have to do this on my old echo cs-302.

Good information. Never did one of those. What do you look for to decide what size and thread to use? Do you have a gauge to check size and thread? Thanks for sharing. You always make things look so easy. Not so much for me.

[@donyboy73]

i usually look it up online, also the kit comes with all the matching thread inserts and drill bit

[@gordbaker896]

Match the stud that came out.

[@smigletat9634]

@@gordbaker896 yes sir!! Sometimes you just got to go back to basics/ foundation & K.I.S.S. (keep it simple stupid)

[@alxw88]

Would it be longer term/better fix to time-sert this instead of helicoil?

[@uTubed007]

Should have mentioned best practice torquing of that stud into aluminum to prevent any guess work

[@donyboy73]

just use common sense

[@danielrobert7181]

Common sense is always called for but you got 35 years experience to guide you. Most people watching you are apprentices and don't have that kowledge. Providing that info would be a bonus for all. Love your videos !

[@bcamk]

The bar stud looks shorter and the collar not as deep as the other stud, there is another one listed in the parts list 1138 664 2400 might be a better choice. What brand was the thread locker that was used, looks nice?

[@donyboy73]

thread locker is Loctite

[@johnkosheluk1041]

[@Matt_justlikethat]

On the helicoil u don’t use any locktite? Thanks Matt

[@thomascaulfield9277]

what do you use ob plastic cases is it the helicoil or oversize stud

[@999thenewman]

I have never stripped a stud as far as I remember. Were the nuts forcefully put back on studs covered in debris?

[@popingfish1]

Looks like a brand new stud to me

[@wM70AB]

Hey Dony, I am looking for a used Echo SRM straight shaft gear box... all the online stores have them for $40,50,60. Not worth it on a free trimmer I'm fixing. Do you have any suggestions for a cheap one? Do you have any?

My english is not too good but I am going to try, your videos are very good!! Excellent! Perhaps you can help me, I have a Stihl ms 180 and suddenly the starter rope was very hard, when I remove the spark plug it is excellent, but when I put the spark plug again it is very hard, and it was not like that, you know what it could be? Thank you very much!!

I did a practice run in a 1/2" aluminum plate, I drilled the hole ran the M8X1.25 tap the screwed the helly coil in and the stud does not fit these threads, the M-8x1.25 is exactly the same than the nut that tighten the bar, the threads that screws into the crank case have a different pitch, the saw I am repairing is a MS-230. What would be the size to pre drill and tap?

Great video thanks! Would you use a heli coil on plastic (as I've seen some people do)? I was going to try this for an echo chainsaw with one of these V225000031 bar studs - but the threading is more coarse and I don't know if it would be a bad idea if the thread isn't a great match with the heli coil...

Thank you for all your helpful videos Don. I have two questions if I may ask... Is it worthwhile putting some lock-tight on the helicoil itself? And, you mentioned that you purposely refrained from drilling straight through to the oil chamber... would it be really an issue if the drilling went right through? PS. I'm just about to do the exact same repair on my MS361 and am a bit skittish, and nervous about "screwing" it up : )

[@donyboy73]

might be good to use loctite, if you drill right through it there possibly could be a bit of oil that may come out
