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 chainsaws, weed eaters, weed wackers, string trimmers, grass trimmers, line trimmers, hedge trimmers, strimmers, brush cutters, leaf blowers, or four stroke, four cycle units like lawn mowers, lawn tractors, snowblowers, pressure washers, generators, ride on mowers that need 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 RUclips and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!
I want "DON THE SMALL ENGINE DOCTOR" on RUclips to save you time, frustration and most importantly, MONEY with my HOW-TO videos!

Oops you were correct clockwise sorry amigo 😅
One of the best "how to " videos I've seen. Right to the point and extremely well done.
Thank you
Before stripimg down the clutch etc. use a piece of electric wire, 1.5mm and try to unblock the oiler hole as far down as you can, then use a piece of 25lb fishing line and do the same, the fishing line will go around the bend right through to the oil pump and clear any blockage there. 99% of the time this is the cure.
Thanks. I put air to the hole after wire. Working
I don't often comment on video's but yours is so perfectly done that I must. Thank you so much for you're excellent demonstration and commentary. Can't imagine it done better than this!
Agtee
Great demo very clear instructions
Agree that was flawless
Great video and very clear instructions. Had same issue on my saw, stripped it down and replaced rubber pipe. Later found it was the oil cap that was leaking. Now replaced and all clean underneath.
My god! That poor saw never seen a lick of proper maintenance. Imagine how reliable it would be with only a little maintenance. Great video!
excellent video. Great close up shots, good detail. excellent editing. Thanks for another good video.
thanks james
Dony - do you have video which shows how to replace the oil line on a Stihl 036?
Thanks

Well-made, no-nonsense, professional video. You don't waste our time with needless conversation like so many of the other self-help videos out there, you get right to the point and tell us what we need to know. Great camera angles, good closeups, good lighting, attention to detail, and excellent descriptions of the procedures and what to watch out for, including safety recommendations. Excellent job, keep those well-made videos coming, they are greatly appreciated!
Well said. !
This video stands the test of time. The close ups and detailed explanations instill confidence to make these repairs by the owners. The Stihl chainsaw we own still has a plaque that reads "Made in Germany". I was using it last year to help my neighbor clear a large downed tree, but most of the way into clearing the tree it stopped oiling. It's been sitting for a year now and this spring I can finally sit outside, hopefully a warm sunny day, and get into this. All I need is the 27 star tool. Thanks again for all the details, including tools and screw locations. And, this isn't the first video of yours I've seen. Much thanks DB.
I’ve been watching chainsaw how-to videos for a long time and this one is the absolute best I’ve seen. I very much appreciate your approach snd methods …thank you 👍🏼
This video is perfect! I have an MS-250 Chainsaw, and noticed the chain wasn't getting oil. Followed your instructions. Turns out the O-ring on that plastic piece was pinched. Not installed correctly at the factory. I ordered the same parts you did, just in case. It's really quite easy if you see someone do it once or twice, and know what to expect. Thanks for these great videos.
Same here Ken. That O ring on mine was a mess from the factory
Huge help to simplifying what seems like a big project. Love your detailed and easy to understand videos!
I definitely need to do this with my chainsaw as well. It's not getting any oil to the chain. So thanks for the video. It is a big help.
I don't own a Stihl. My chain oiler is working properly. I watched the whole darn video. What is wrong with me?
A quick look through the comments says it all for me. This has to be the best "how to" video I've ever seen. Every detail is covered in such a professional manner, it was a joy to watch. Thank you donyboy, your efforts in producing this video are greatly appreciated.
thanks, I get to the point quickly, no bs
I do not even have the problem but the video is absolutely excellent. I had to watch the whole thing!

I was about to write this comment but I'll simply agree with you whole heartedly
There is a shortage of people like you sir!! Thank you for sharing your knowledge. Would say more but my saw is fixed and Im burning daylight. Cheers mate.
In the US I was sold a 1123-640-3201 oil pump. I believe it takes a 10-32 machine screw rather than the M5 used for the 1123-640-3200 oil pump shown in the video. Great video.
I owned a Stihl for over 20 years now and it never even occurred to me it had an oil pump. Now i got something else to check out on it. Thanks.
Another very informative video. The explanations and camera angle and close ups are excellent for us backyardigans when it comes to us making these types of repairs on our tools and gear. Thanks for doing these.
you're welcome
Without question, this is by far the best saw repair video I’ve ever seen. No BS jabbering, no annoying elevator music, no advertising. Every detail perfectly shown. Each step of disassembly and reassembly perfectly explained, right down to specific tools. Perfect camera placement and clear audio of great diction. Stihl should put you on their payroll!
thanks Wayne
donyboy73, thank YOU! I was about to toss my MS250C in the trash, but now I’m confident that I can have it working like new with no problem. The oiler is the only problem I’ve ever had with this saw, but it was driving me crazy.
these long videos are the ones i love. Thankyou
thanks
Thank you, it's one thing knowing your stuff and another being able to teach it - you do both BRILLIANTLY. Best teaching I've seen on YT full stop. Given me the steps and confidence to tackle a dry 044. Echo your oil /bar check, taught to do it as a safety check on every saw start. Subscribed without hesitation.
Wow, great video and great information! Thank you thank you thank you for this info.. Don’t know if I have the confidence to tackle the oil pump but your video explanation is top dollar!
If there is a YT award for 'Best Small Engine Repair Channel', Don would win hands-down! Beautifully filmed and explained.
My o29 stihl farm boss stopped oiling the chain....and new gas line is leaking gas...brand new still line...leaking....🤔
Chain bar was stopped up n gas tank vent line missing causing gas leak
I spliced my cracked fuel and vent lines with the tiny copper tube coming off a refrigeration coil
Excellent video. Clear, concise, comprehensive, good pacing, doesn't waste my team. This is how to do an instructional video! Subscribed!
You produce a very nice and informative video. Good job. I also like the fact that you do not edit out any possible scenerios that could occur during the process, the flying clip for example, or a forgotten screw. This happens to the even the best mechanics, I appreciated that fact, some mechanics let their ego get in the way by not showing simple little mishaps that can happen. Great job, thank you! Subbed BTW...
My STIHL technician taught me to check the depth of the oil pump prior to removal, and to reinstall at the same depth - so it works properly.
FYI, Stihl molds a small "diagram" of the bottom of the oiler pump on most saws, to help to align correctly when reinstalling. You can clearly see this "diagram" at 8:54 between the oiler hole and left edge of the screen. On the MS250, there is also a small divet near the hole to help with alignment. Again, this can be seen at 8:54.
Yes, he put a piece of text over the video describing the icon. I don't think he noticed the icon when recording but in the edit added the text. Good catch!
You start pointing out that it is good to blow clean the saw, and then You pull the oilpump and the hose out in a mountain of sawdust, I wpoud blow clean around these sensitive parts before pulling it apart, but otherwise very good vid's as usuall Mr D
very thorough and easy to follow...really enjoy your videos..
thanks
*OUTSTANDING DETAILS! NOT MANY EXPLAIN THINGS LIKE THIS! OUTSTANDING!
Thankyou so much Donyboy. The other day, I replaced all of the oiler components on my MS230 which had stopped supplying oil to the bar and chain. Your very clear explanation and instructions made it easy. For those in the UK contemplating any DIY maintenance on their Stihl machinery (or indeed most garden machinery) I can recommend L&S Engineers for all parts supplies. Clear parts diagrams on their website, competitive prices and quick delivery. The combination of DonyBoy's clear instructions and the availability of parts makes servicing and repairing your own machinery a walk in the park.
Thanks, Dony!
Fixed my chainsaw following the video. It took the whole day though, but now it's all working great. Half stripped a screw, but that's my lack of experience... Thanks again!
Kyle247l
Awesome video Donny. I needed this one. My chainsaw has been leaking oil for years !!!! Hope to see more sthil repair videos. I don't see many on line. Thanks for sharing.
you're welcome
Thanks Dony !🍻
Thank you for this video.
I have a MS290 but many of the steps are similar. The pump on my unit was actually easier to remove, just two bolts and I didn’t have to remove the handle. This video gave me enough info and confidence to do the job.
My pump was starting to bind and that caused the plastic worm gear to eat itself. Two parts and back up again. Thanks!!!
This is another great video. Clear, concise, and complete. The job itself is a little more involved than I would normally be comfortable taking on but I think I could do it by referring back to this video and taking pictures as I went. Thanks for another very informative video.
Great video, and info, SO MUCH MORE help then talking too the service desk personnel..
Very well done, Don :) I don't understand why some people have dislike this video... Thank you for sharing!
Hi, thanks for a great video with regards to replacing the oil pump and o ring causing it to leak, most of my saws do, so will get onto that job 😁👍
keep up the good work, fascinating videos👏
Hey Don, just to let you know that I think your videos are really great! With these chainsaws being so expensive to repair I surely appreciate your methods! I just picked up an MS 260 used. Downsizing from my 036 which I had for years and it was just far too costly to repair or replace! Any advice on the 260? This saw is clean and barely used. What are the best things to watch for on this saw, as I am unfamiliar with this model. It is a Pro 260. Should I be making any before use precautions....changing plug etc?
Thanks!
Jay
A true professional.Beautifuly constructed video.Operaters like me want to understand how their
Gear works and carry out repairs
Themselves.Truly priceless!!!
Don, a really nice job! (Oil Pump Replacement - Stihl MS250 Chainsaw) I too, enjoy watching longer videos, and the procedures that can be apply to other STIHL models of chainsaws.
Thank you, cheers! :-)
Do you have any ideas on how to increase the amount of oil flow to the bar and chain for a STIHL MS362. It is 3 years old and out of warranty. I have turned the flow screw all the way to the right (clockwise) and it still doesn't spray oil that can been seen on a piece of wood. I do see oil coming out of the flow hold when the bar and chain is removed. STIHL indicates they had to reduce the amount of oil to comply with the Federal government laws. I feel that the bar and chain fail to receive enough oil to prevent damage to both. Any ideas would be appreciated.
After your saw sits for a while it leaks out the oil that is in the pump then you start it and it doesn't pump because it lost it's prime so take the oil cap lose to let air in and see if the oil starts to flow again. If not working next pull the oil feed line off see if oil comes out? Oil will then start coming out the line, put line back on. Next super common thing is your bar oil hole is full of saw dust, clean that out.
Great video, Donny. Info is complete and concise. My chainsaw has been leaking oil, and, now, I know to go check the oil connector. Thanks for the great info! You've earned a sub.
Very clear explanation of how to - gives me great confidence in doing it myself. Best of all instructive videos. Thanks very much.
Excellent video,very nice voice.
Thankyou
Good stuff, learnt a lot! Thanks.
Brilliant video! As a relative newby to chainsaws, it's really interesting to know how bits and pieces work and how to troubleshoot, repair or replace. Many thanks for sharing your knowledge with us.
Hey Doc, Thanks for the video. I'd like to know why you recommend to not run the engine at speed without the chain/bar installed. As you indicated during your troubleshooting, it would be a great easy way to test for oil flow.
You don't need to run the engine at all to test the oiler - just rotate the clutch drum (without the bar and chain, and with brake off) about 10 turns clockwise, and you should see oil flowing out of the hole that matches up to the bar oiler hole.
What a lifesaver...my '94 025 will get some beauty treatment thanks to your video. As many said, great detail/editing.
Great video. This saved me from buying a new saw. The repair was easy and best of all it worked. The saw oils fine now.
For additional help in lining up the pump during replacement, there is a symbol next to the hole for the pump. It represents the positioning of the new pump with the groove on the pump facing the correct direction. I like all of your videos, you are very thorough and explain things every step of the way.
I came here to say that! Have a thumbs up for doing it first! :)
This is an excellent video, probably the best I’ve seen. Thank you so much for taking the time to post this!
Some people aren't fit to own anything 😮 , hopefully, mine stays OK but this is an excellent video for those of us who might need a reassuring hand with a job on this side 😊👍👍Thank you Sir😊
Just want to thank you for a great video. I have a machine shop and know my way around alot of products. To day I disassembled my Stihl ez start 250. With notes from the video is was very easy. Thank you for saving me alot of time and money.
Sometimes also the oil pump needs priming after replacing the oil tube and filter. That can be made by using a pressurized air pistol to the complete system at the oil tank cap to force the oil to start flowing. Some saws do not run oil before this operation.
Thank you you just save me a trip to the mecanic
EXCELLENT VIDEO! I sure do like all your videos on Small Engines. They are so very informative and I also like that you provide the part numbers and links to Amazon. That saved me a lot of research last month when you gave me the Amazon link and Craftsman model number for a Sears LT2000 mower deck spindle.
Your videos are absolutely the best! So clear and excellent description. A repair shop manual drawings are tough to understand. I often recommend your vids. You've saved counless dollars and down time.
Been a while since I've watched one of your videos... Great to see things are still top notch... I'm off to find a broken saw to fix! lol
@9:00 do you see that ring impression in the plastic on the left with a cutout mark? That's the oil pump alignment reference mark.
No need for sharpie marks. Just line the pump up using that reference.
I came here to say that! Have a thumbs up for doing it first! :)
I think he did that so we could see it on the video.
Super great Video!!! awesome video.. I know nothing about a chainsaw and now I feel like I'm a pro after watching it. thanks!!!!
Toko BoBo ha ha ha ha ha ha you are a pro ha ha ha ha
Last week I bought used stihl chainsaw and I want just clean up, but, found oil leaks, this video help me, to understand from where and how to repair. I'm doing everything very excited and when I'm done, I was very happy that I doing by myself. Thanks for the video, really cool!
Just a great DIY chainsaw repair video! When my oiler stopped, I didn't have a clue how to fix it. I found your video, enjoyed watching it and knew immediately I could do the repair because of your excellent explanation and high quality videography.
Two things I found by accident during my repair: The handle bolts will fit the oil pump for extraction, so you'll always have an extractor tool.
And, to clean the small oiler hole, I inserted the oil straw attached to my can of WD40. Give it a good squirt and it flushes out debris.
Slow, steady and deliberate description. Great video on the subject. Great close up and editing Donyboy.
Anyone know the name or part number of the plate behind the clutch/before wormdrive? My 025 is apparently missing one. Any help appreciated.
Very good will be able to do this myself now,thanks for you time and skills
Tremendous video! Very well done! I see you made this video about 3 years ago... funny thing... that's almost as long as I've been manually applying oil to my chainsaw! ... I know, but I follow one motto: _Never procrastinate until you absolutely have to._
even an idiot like me can fix my saw....very very good video tutorial....Thanks!!
Thanks for posting Donyboy. I have the same chainsaw and that breakdown was perfect. My chainsaw throws oil after I took it apart and cleaned it right down to the pump. Not sure if it is throwing the correct amount of oil. Hard to tell if the pump is weak or not. I really appreciate all your videos.
Great video, very clear pics & informative,i really enjoyed watching. THANKYOU, IWILL BE BACK
Thank you donnyboy, that worked a treat for me and saved. E alot of headakes, great video 👍👍
My MS250 doesn't put much oil on the chain even when everything is clean. It's puking oil out the bottom of the saw and also the area below the muffler, then it runs down the front of the saw. Sounds like my o-ring is bad, and maybe the plastic piece that the o-ring installs on.
AWESOME VIDEO!
thank you, i can't find such good explaination in France! merci beaucoup, très utile, vidéo très dur a trouver en français, mais pas besoin de traduction, la vidéo parle d'elle même!
thanks for posting. Great video.
Such a great video! Nobody, and I mean nobody, does 'how-to' videos better than you. Thank you so much. Never stop.
Great video, excellent tips. Thank you :)
thanks
Excellent video, thank you! I have that same model saw and mine leaks oil when I store it overnight.
Outstanding explanation of this repair. I learn a lot from your videos. Thank you for sharing them
thanks craig
Thank you up loading this tutorial vd. It is is very thorough. This is exactly what I need to replace for my MS260.
Thanks for sharing, I have a set of Stihl chainsaws, and it is great to understand the mechanisms involved in their operation. I really appreciate a pro like you taking the time to educate us laypeople on the inner workings of our equipment. Maybe I will do my own maintenance on my 290, of course, my 660 will continue to get professional care.
you're welcome gareth, make sure you are subscribed
donyboy73 You betcha! And I will tell my friends also.
Great Video! Very easy to follow and very in depth.
*El video esta bien explicativo y se ven los detalles de las piezas. Felicitaciones. Angel*
Nice job. I've not had to do any major repairs but I know where I'll start looking for great advice and instruction.
love your videos dony very helpful keep'em coming
Good job brother nice video I do small engine repair to and chainsaws and it drives me up a wall when people are blowing stuff off all the crud oil dirt in their shop it was nice to see you go outside and blow it out outside I try to keep a clean shop
Right on!
@donyboy73, very interesting.All I have seen to remove oil pump is, remove clutch.At which, get behinf it and into pump to remove.So, you can simply remove this by the under side of saw?
Just noticed today my 250 is not getting oil.Cleaned hole in bar, cleaned oil hole on saw etc.No go, start saw and no oil.Although leaks oil some from bottom of saw? Anyhow, dropped off today at Sthil.See what they say.But next time looks like I could do the pump thing.
So what is he cause why pump itself craps out? Seems like a issue with these newer saws.
Ball park, Sthil parts, whats a bar and chain run$? Curious about that.Have not asked around yet.
Really good video! I have a Stihl 025. I have replaced the oil line but I seem to have a lot of oil leaking from that little hole. No oil seems to be leaking around the oil pump area. Being my first chainsaw, I have a lot to learn and dying to use it but seems to be a lot of oil leaking. Any suggestion? Thanks!
Thanks fir the tips mate .very help full.old jimmy west australia
Excellent ! Im going out to the garage now. A friend gave me an 036 Pro that is not oiling. I found the clutch drum is badly worn.. too much side play on the shaft.. probably not able to drive the gear because the wire came out of the notch... I will be ordering parts. Thanks for the video.
EDIT: This saw had a melt down in the clutch area.. broken drive gear wire, broken hose coming off oil pump, melted dust cover.. somebody ruined a good saw. Probably not worth fixing unless I buy Chinese parts or find a parts saw.
Great step by step instructions. Seems like a complicated arrangement. Thanks and have a good weekend!
thanks steve
We have a 311y... turning clockwise does not remove the clutch - it never actually gives resistance. Is this simply a difference of models? Or are we doing something incorrect?
As always, great video!
My MS 250 is less than a year old and it'd burn the chain about every 5 min when cutting into a log. Hickory, oak, maple or pine. Would start out GREAT!! and in a few minutes start burning up the chain. Clean rinse and repeat. Oil flows good if you're not cutting wood....haha!!! I need to bring it in under warranty, but I know what I'm gonna hear. "works good, we can't find anything wrong". Oil comes out fine, I've cleaned bar guides/slots and even squirt some bar oil all over for a bump. It just doesn't like 2-4 minutes straight of cutting logs. New chain and and all.
Foolish me -- if I had done more research before buying a 10-year-old MS 250 I probably wouldn't have got it. Since this video has had more than a million hits, obviously the Stihl 250 has a real big problem with its oiling components -- as I found out with the 250 I just bought! I got it as a backup for my 19-year-old MS 290, which has seen a lot of wood (6-7 cords a year), but you know what? It's never had a bit of trouble with its oiler. It had a carb problem, but that's fixed now. Anyone want to buy my 250 from me so I don't have to tear into it? 200 bucks and it's yours. (great video, by the way!)
Hi. Very nice and clear instructions. I have an oiler problem with an MSA220. Seem like the pump is the same, but the clutch looks a little different. Got any experience changes oil pump on the new MSA line? Any thing different to the process?
Love it!! Excellent video. I followed your instructions exactly and solved my problem. I feel empowered. Thank you for putting in the effort and sharing. You’re the best!
Why did you not use the 025 oil pump, instead of the ms 250 oil pump. They are identical, but the 025 oil pump is a high capacity oil pump. The only difference is their color - the 025 oil pump is gold in color. My 250’s have the 025 oil pump in them. All the new Stihl saws have low capacity oil pumps, pursuant to EPA directives.
Just installed a high volume pump in my MS250. My saw has NEVER oiled the bar and chain that good. I’m honestly convinced my pump was junk from the factory. Had it in the shop twice and they said it was fine. But doing the ole’ cardboard test, I never had oil slinging onto it. But I sure do now 😮!
I apologize for not reading all the comments, but I'm looking at a Stihl ms180 or ms 250 to replace my older 026 that I sold. I was wondering how much use the saw got out of it before they chain oilier went bad? I had a similar issue on my 026, but that was just a slogged oilier port. Easy fix. Thanks!!
