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 UA-cam and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!

Hi my friend Is chchainsaw parts in amazon is good
@@user-fo1tx5bk7b some parts on amazon and ebay are not good
@@donyboy73 How can I distinguish good from bad? Thank you for the answer
it's like russian roulette, hard to tell until you try the part
@@donyboy73 Thanks again The problem The purchase cost is acceptable, but transportation to Iraq is more expensive than the product. In any case, I will choose the pieces based on the evaluation of the users. My name on Facebook is waad Ahmad. I sent you a video about the parts that I have.👍👍
This is an excellent tutorial! Step by step and great camera work! Fixed the fuel leak on my MS290 and my saw is running much better! Thanks for posting!!👍
5 years ago and still helping. My MS250 acted up, changed the plug, got everything together and it leaked gas. Not my fault, yay, tracked leak to this line. thank you
Thanks-a-million, Don. You made the repair a LOT less complicated and intimidating than it could've been. I figured it would be a nightmare, slice up my hands, and recite a dictionary of malicious swearing. Thanks to your tutorial, I should only need one part, and about an hour.
I expected a challenge when I got into my MS280. I was pleasantly surprised that there are 50% fewer parts to remove, and the job was done in five minutes. Thanks again!
I was ready to take it to the shop till I saw this. I usually do my own repairs but for some reason this worried me. Thank You. Very clear.
Good Job...I'm still running my 036 PRO. year 2000. Time for a Fuel Line. Great video. It amazes me that I call STIHL HOTLINE quite frequently. As long as you have your serial number...They can find your correct parts. . Call center in Athens, Greece Thanks for the great video
Best tutorial among many. Too good to be true, but it is real. Best photography and sound recording.
Perfect diy movie. Thx, pushing in the new hose not that easy , made a special plastic tube (from a silicone nozzle) to put over the petrol hose and so pushing it in more equally.
Super clear & precise. Just had the same fuel pipe fall to pieces on my MS 290 - thanks alot Don, you saved me a packet !!! From the U.K.
*A good video with a very detailed explanation to change the fuel hose of my ms 290 congratulations. Angel*
Thanks. I have saved lots of my hard earned cash learning from you in looking after my Stihl chainsaw. Cheers.
Best video on how to change this fuel line. Exactly what I needed for my ms290. Thanks Dony
Super helpful video. The basic procedure would apply to numerous Stihl saws.
Hey, Dony. I followed your instructions to the letter after diagnosing the problem with my chainsaw. It worked perfectly as you illustrated. I ordered the genuine Sthil fuel hose from a local dealer based on the part number. Perfect fit. Thanks very much and keep up the great work you do.
Thanks for another great video. I changed the fuel line on my 029 last night and it was fast and easy thanks to having watched this video the day before. Mine was cracked but this video helped immensely. The tip about peeking in between the tank and the saw body to view the fuel line where it enters the tank was helpful. I observed it being dry and then getting wet with fuel as soon as I turned the saw on its side, so I knew what the problem was. Thanks Don.
I've replaced the carb and fuel lines on a Poulan Pro and I did it with no screw ups. LOL! I've not done anything with my chainsaws do to other priorities. Bought a Sthil clone and it's still a virgin. This breakdown and your insights will help when I peer into the bowls of the beast. LOL! You were the first guy I checked out when I had to trouble shoot my screw ups. Burned up my Poulan pro. Breaking it is how I learned to fix it. Thanks!
Great video. Maybe do one on the oiler system for the bar? I've seen so many bars burned up because people are unaware of the importance of keeping this clean and flowing. Thanks for taking your time to produce great content and educating others.
Michelle R he has one tutorial about whole oil pump for chain lube. Excellent videos by Him.
Thanks, Don. Very helpful.
Nice tutorial. Saved me some time thinking it was a carb jet issue. Had a tiny crack in the line at the exit of the tank. Ms310 here.
Great overview, thanks! Just tuned up my Stihl 310...your video is stihl relevant (sorry...)
Great to hear!
Ty learned all I needed to. It was great that you went right to work with out giving us a half hour story and then fast forward to shorten your video. 🤗
lol
Thanks for another great video very informative 😀
Incredibly helpful to repair a previously disassembled unit. This saved me 10X time to fix. Thank you for taking the time to document.
Great to hear!
Change everything yesterday running great but leaking fuel at the tank. I figured out the problem but not the fix. THIS IS EXACTLY WHAT I NEEDED TO SEE. Ordering part today.
Recovering from hurricane IDA down here in Louisiana.
Holy cow there is more to that than I would have thought.
But I'm glad you mentioned the magic words "Impulse Line".
Because when I was 12 years old I had a go-kart, 2-stroke, with a carburetor that I never understood very well because it didn't have a float bowl or a fuel pump. It was the only "impulse line" type carb I've ever had on anything, and I never understood how it could even work at all.
So now with the magic words, I can read about these carbs and figure out the stuff I wish I had known then.
Better Late Than Never!
Thanks!
Yes, the amount of people who bought stuff into the shop where I worked and said "oh it's just a xxx amount of time to fix right" they never worked on small motors yet they were the experts and not the guys who worked on them all day. Then they complained when the bill came in. One guy bought two saws in and wanted me to make a good one out of two (both were pretty stuffed), I had to use parts from another parts saw we had in stock so he had a decent saw, he complained bitterly that I did that so I took our bits off and just threw whatever he had together. I told him straight that both his saws were stuffed and said I offer no guarantee that saw will work.
@@MegaDirtyberty Then learn to say no to junk - based customers. Make no promises or guarantees.
@@999thenewman I didn't have a choice, the boss bought it in and said make one out of two. The customer returned a few days later to pick it up and was told what was done to it then the boss came at me because the customer was unhappy. The boss knew what I had to do to it with regard to the extra parts.
Thanks donyboy73
great video. simple and concise. but it looks like you put your air prefilter in upside down. in winter the prefilter should have the snowflake pointing up so that the grilled part allows warm air to be drawn in from around the motor so that it can warm the air being drawn into the carb.
Best tutorial on this subject. Great photography and clear explanation of the method.
I live in Tasmania and own the MS 310. This made changing out my carb a breeze. Many thanks.
Wow. Professional grade tutorial--of the best DIY presentations I've ever seen on Ytube. I hope this will take care of a fuel leak that was subtle, and hopefully the cause of failure to start without priming the carb directly. If so, I'm off to cure my MS 290 with confidence. Thank you for sharing your considerable skills with those of us in the trenches.
Needed to change the carb after sitting unused for many years, great video, thanks, made the job very easy.
TY for making this video!!
You made it so easy to replace a fuel line on a chainsaw .I've tried for an hour to make that fuel line on Stihl 044 go through the hole at the neck where it stops , there was no way Donny Sir, unless they sold me the wrong part .but this is OEM. For the 044 at the dealer .
Great stuff I’m a little surprised you didn’t replace that air filter it looked like it’s seen it’s day.
Excellent video!
A very professional and helpful video! Precise instruction and easy to understand. Great images!
You just saved me a lot of money.... thanx a lot!
Greetings from Sweden 👊
good tips. EXCELLENT photography! Thanks
Good Video Donyboy. the photography is very clear and audio and dialogue were great. On on way out to my shop to get my saw back in business.
Great video.thanks for sharing
Thanks for the GREAT video. I wondered how to get that done and thanks your your video it's done and fixed. Many thanks!
amazing. thanks! i replaced the hose on my 034 with your tutorial. it's very similar to your video. different hose part # but the principles are the same! thanks again
Another great instructive video, well narrated with clear video. Thank you donyboy73!
DonyBoy is The Best! Thanks for your great detail and precision camera work.
thanks and I won't set the night on fire!
Thank you
perfect. Many thanks. You answered all my questions
Thanks for this video! Got my saw up and fixed for $8
Had I known that it was this easy, I would have done it long ago.
Very well explained and filmed 👍🏻
Howdy Brother. I have 4 stihl now and no one is working. 😂 It would be easyer to have only one, because now its just overwhelming :-D
Instructive video Danny
Just watched this and was able to do the same on mine and my dads ms290. Thanks
EXCELLENT video Sir!
awesome video! Great camera work....
What is this? A real demo?! Rock solid video!
Thank you! Great job!
Thank you Don .
I plan on buying an MS 251 soon
They're supposed to go on sale next week 😁
Nice video. I am sure this will come in handy in a year or so when mine will need replacing.
Great video and explanation. Just one thing caught my attention, when you were talking about that plastic part on top of the air filter that you can flip for winter and for summer. I think that you said it backwards, when you turn that part so the holes are between cylinder and air filter housing that is a winter setup because it allows warm air from cylinder to get to the air filter area. And when you flip it so it's blocked that is a summer setup because you don't want hot air from cylinder to get to the air filter area when it's already warm outside.
Yeah, screen on top means its for summer operation. It even has a embosed sun icon stamped on the screen side and snowflake icon on the other side to remind which is which.
I just stumbled upon this. You are right. It is not to prevent air from coming in at all. It is to allow hot air from the cylinder to be sucked in.
Keep up the great work.
Thanks for the great video. Very helpful!
Good job amigo
How's she goin'? You mad e look pretty simple. Well done thanks!!!
Great video. I'm troubleshooting my MS 391. i think its a fuel vent problem as it will do a cold start run for a while and wont restart even when i crack the vent. having a heck of a time finding it.
very educative thank you regards
Awesome video , step by step very helpful . I'm about to do mine , thanks donyboy73 .
Thanks for posting this saved me some money, ? I have 029 Super this did not have the metal flange on the carb should it have one?
I put the grommet in with a little 1184 on the seating surface and then pull it into the tank with my hemostats. This keeps the grommet fro leaking and there is usually enough oil left around the hole in the tank to keep the grommet from being permanently attached to the gas tank. Another thing to watch if using an AM fuel line is - did the line go all the way on the carb fitting. If not it can lengthen the line and cause a kink right behind the carb.
My hero 😻❤
I smear a thin coat of 1184 on the hole in the tank to ensure it will not leak after the fuel line is in the tank. It also helps the grommet’s entry into the hole.
I've found Threebond 1184A, and Threebond TB1184. Which should I get and why please? Thanks.
@@johncollins8304 Threebond 1184 is what I use. Let it dry for 15 minutes and then put the parts together. A thin coat is all that is needed. Stihl uses Dirko HT but it does not keep well once opened. I keep my tube of 1284 on my desk in the house, which is air conditioned. Leaving any tube of RTV type sealants in a non air conditioned space will lead to their premature hardening, opened or not. I keep all sealants/glues on my desk in the house.
i see on my side 14 people did not like the work you done.....Dony i LOVE your work step bye step ...forget about the jealous persons the 14 must only be jealousy ....i am going to do that kind of work but the only thing my stuff its not OEM but its ok...keep it up nice job.
well done
Does this video apply to the 039 as well? I'm assuming, mine leaks when full and on its side. Thanks, that was a great instructional of the repair.
Don just an overall excellent video; pace, angle of photos, and sound.
Like the explanations along the way.
Can those air filters be cleaned and how often do you recommend changing them?
Where can service manuals be purchased?
It's not enough to set the plate to summer and winter positions, you must also flip the shutter 180° located by the spark plug so it draws hot air during the winter. All it tales is removing the spark plug boot and a screwdriver to take the shutter off and flip it to open a port.
Like Donyboy73 says, buy the Stihl fuel line. I bought an aftermarket fuel line, it lasted 5 months and cracked.
A lot easier than the old saws I had.
Why would anyone dislike this?
I put a little 1184 on the gromett grove before I put the fuel line in the tank. This insures it won’t leak, again. I pull the line into the tank from the inside of the tank until it pops into the tank. The 1184 helps it to go not the tank.I do the same thing on oil lines that go into the bar oil tank. I degrease the holes with break cleaner an a Q tip before I put the lines in. I also pressure and vacuum test all gas tanks, fuel lines, gas cap and tank vent. They better hold 7# pressure and vacuum.
Sounds exactly like mine :)
Use a little grease helps pull it through
chain brake on ALWAYS, BUT GOOD VID
Great video. Very helpful. I wish the rope on my MS290 pulled as easily as yours! When I take the plug out, it pulls fine . . . but with the plug, I feel like I'm wrestling a bear! Very hard to pull. It runs great once I do get it cranked. Suggestions? Thanks!
Great video. Would it be a good idea to spray down the carb with some cleaner while you have it out? Ty
Thanks for the educational video. I think you should have included the fuel filter in this video. Or do you crazy Canadians run it w/o the filter? Lol
Spoke to soon. You mentioned 290/390. I have a 271/291. Completely different setup. Stihl dealer shows 2 piece fuel line with a connector. Looks like i have to take a lot more apart than you did and not as easy. My first thought was probably correct. I will keep trying. Any suggestions would help.
Excellent ~!! :-)
Hey Dony, do you think you could do a long term study/review of K100 vs Stabil, Seafoam and baseline ethanol-gas? I just came across my chipper that refuses to start. (had gas in over fall/Winter but fuel shutoff). I dropped the bowl/float and found clear crystals in the fuel. I drained out the tank (hand syphon) and noticed alot of this "debris" on the bottom of tank. I don't know how to clean it out (have to remove the tank or flush it?) but I think I used Stabil or Seafoam fuel dryer/preventer. Preventer at starting, right?
Smashing :-D, dry as a bone and ready for work again.
my new (few run time hours) farmertec 660 saw leaves a puddle of gas under the unit. originally, i thought the gas tank might be cracked so i removed the gas tank lower unit and inspected it but didn't find a problem. i left the tank off the saw for a few days with a 1/3rd tank of fuel and no puddle was noticed. i reassembled the tank to the saw and let the unit sit on my work bench for a few days and then noticed more gas was puddling. do you have any ideas of what to look at for this issue? i looked at the check valve on the tank and confirmed air was flowing in a single direction. thanks for you expert guidance!
Do you have a video for replacing a new fuel line between tank and carb on MS291?
very god
I'm going to be replacing the fuel line on a stihl 029 super farm boss. It looks the same as the machine you worked on. Any tips on replacing the impulse line too?
I replaced the fuel uptake line on my MS660, however it is still leaking. Would it be possible to add some sealant around the new uptake line? What would be recommended?
Hi Don,
I'm a little confused by something you mentioned in this video on the MS290, could you please clarify it for me.
This video differs to what you showed in your summer/winter mode video.
In this video you said 'it's winter here in Canada', and installed the air dam with the vent holes facing up, and the hole next to the spark plug was closed off?
In this video you said, 'in summer' you would put the vent holes in the air dam facing forward for more air flow'?
This seems to contradict your other summer/winter video:
For winter mode you showed the vent holes facing forward to allow warm air to flow past the carb, stopping the carb freezing up and allows quicker warm up etc.
You also flipped the black flap next to the spark plug boot to open up the air hole for winter mode.
In summer, you showed the blank part of the air dam should face forward with vent holes facing up to block warm air flowing around the carb, and the hole next the the spark plug boot has to be closed off to make all of the air flow over the cylinder which promotes best cooling?🤔👍🇦🇺
Just replaced oil n fuel line on 029 farm boss...1999 model
Don, I'm trying to repair a serious leak at the fuel line grommet on my Stihl 026. I have gone through 2 new OEM fuel lines that STILL leak at that grommet. Could the MS290 fuel hose be worth a try? Any reason it definitely wouldn't work for the 026 application? Thanks.
another great video on friday, stihl is great chainsaw , just REMEBER to have 2% oil in the gasoline, OR ELSE THE MOTOR WILL FAIL
hi, i have replaced the motor and carb on my ms390 and its bogging. i have tried adjusting the carb and still having the problem. do you have and tips what i can look for?
