Easy to follow and thorough step by step tutorials do it yourself (DIY) videos to help you with your broken lawn and garden equipment including snowblowers and zero turn mowers.
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, zero turn mower, 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"!
I want "DON THE SMALL ENGINE DOCTOR" on UA-cam to save you time, frustration and most importantly, MONEY with my HOW-TO videos!

Clear, concise, and short. Such a blessing to watch. the best carb cleaning how-to for this era of walk-behind. Mine is a model 8071, from '81, and this explained the process beautifully. thank you!
+David Ploss (TheWorkingReader) thanks
The best how to video I've ever watched. Straight to the point. Love it and learned a lot, thankypu
Great video. Everything you need to know, without the unnecessary banter. Well done!
I have a two stroke lawn boy. The thing cuts anything in its path. 25 years old. Never stalls, starts on the first pull. Love it.
Simple, short precise video on building an old Lawnboy carburetor, exactly the video a non-mechanical guy like me needed. Thanks!
Im restoring a 5277 lawnboy and this is the best video out there. Thank you very much!
Its missing the little clip to suspend the float pin so I have to find one of those and an air filter cover.
I love these small engine projects..Thanks again!
I have a Lawn Boy that is similar to yours that I bought in 1981. It's the only mower that I've ever owned. These last few years, it's been harder and harder to start, especially on cold days. I dismantled the carburetor and cleaned it out, following your instructions, and now it fires up on the FIRST pull. Thank you for your help!
This is the best carburetor cleaning video on youtube for older 2 stroke Lawnboy's. I need to do this tomorrow, thank you very much.
I do not know that I can attain the skill level that you have, sir, but your video rocks! Thank you! I have a Lawn Boy 21 High Gas Walk Behind Push Mower with Kohler Engine that it clogged. It came from Home Depot and I have only used it three times. After the 2nd use and the winter, it had to go to the repair shop. About 2 months ago, it fired right up, and 2 months later which was yesterday, it would not start. Now, I am going to go read the owner's manual (gag!) and see if there is a fuel line switch that may have been turned off as I struggled to lift it back into my storage shed. Thank you so much, Mary in Austin, Texas.
Hey Donyboy, just wanted to thank you for this. I had a 5247 (1980) that wasn't working passed on to me and I was able to clean the carburetor with confidence thanks to your excellent video. Much appreciated, Doug
Thank you for the video. After watching this I did mine and now it works perfectly.
I wish I would have found your video yesterday! Lol
I did exactly what you did and
Made a old lawn boy come back
To life!
Really wonderful video. I only knew it was the carburetor because someone told me. I know nothing about engines. I followed the video with no problems. It was very clear. Thank you.
I started cleaning my carb, and realized I didn't know what I was doing. It had been years since I had done this, and the last carburetor that I rebuilt was a Holly double pumper. It's a little different. I was afraid that I was going to miss something. Thank God I found your video. I had already done what you said up to removing the float(prior to seeing your video), but you took me the rest of the way. You helped me not go astray, Thanks, your a life-saver.
Thank you for this video! You saved my 42-year-old 4970 from the garbage heap!
Excellent demonstration for cleaning the carburetor on the John Deere mower. I have a John Deere mower and now I know how to clean the carburetor and I will try and do the job. I like the oil evacuator system you have to drain the oil from any lawnmower.
I enjoyed that tutorial, I have a 1997 Lawnboy that I paid $300 for back in college to use for side mowing jobs and it has never failed me yet, all I do is keep a 32:1 mixture, Stabil fluid in the fuel tank in the winter, and sharpen the blade once a year old school style with a file. I plan to keep that mower forever.
Thanks for an informative video. Just what I needed to clean out my carburetor,
Thanks Donny I didn't think I'd find anything on this old lawnboy. You explained it nicely for me and make it look so easy. My air cleaner is missing those plugs you showed. What is the little screw (hex head) on top of the carb for under the vane? The mower I'm working on is really really dirty. A real challenge.
Thanks to this video (and the help of many others) I worked on my first two cycle mower, fixed it and made a little cash. It was a Toro, but had the same carb. Thank you.
Spot on what I needed. Hope I can find similar help for an older series Lawnboy carburetor. Many thanks!!
This was a great video. I have a Lawn Boy S21SZR. While the carburetor was a little different I was able to get my mower that wouldn't start to run again after cleaning the carburetor.
Awsome. I just got 3 today, and will be cleaning the carburetors on each of them. Thanks for the terrific instructional video.
I miss my old 2 stroke lawnboy all that blue smoke it poured out, it still ran but all the linkages were broken and the exhaust and stuff was screwed up, still have the engine too i hooked a little lawnmower wheel up to the bottom of the crankshaft and it has just enough counterweight to start with a drill!
Just picked up a free 10550, lawnboy they couldn't get it to start ,so tomorrow morning I'll dig into it and find out the issue, thanks for passing on the knowledge
Great video technique. Very clear. I'm going to help a friend this week with a 2-cycle mower that won't start.
Just picked up one of these for free from a good friend and it's in good shape looks wise but won't start it has spark but I think it's a fuel problem and tks to your video I have a reference...!!!!!
you might want to replace the needle valve and seat, if the tab is adjustable you can pry it up so the needle shuts sooner
Excellent presentation. Very clear and informational. Thanks a bunch
Great video! Amazing how simple and good a plastic lawnboy carb can be, looks like you need to grease your recoil spring, I had a 21 self propelled just like that and love it! Lawnboy's are great!
man I enjoy working on those old tough lawnboys . with a little maintenance once in a while they will run forever
excellent video. mine's been smoking too much & won't run sideways on a hill. sounds like a stuck float. thanks for your help!
If I had known it is that easy I would have did it myself on my 8480. Very good information.
Always what I need
Great video, very thorough and detailed, thanks
Hey thanks for the video. Very helpful. My problem is the choke has become disconnected. I would like to see how it is connected to the manual choke. Switch. Any information would be great
Hey Donyboy73, I recently aquired this same model mower. It runs nicely really. AFter cutting the lawn however i feel like I have breathed in a lot of fumes. IS this normal for a 2 stroke lawn boy or is it maybe running a little off? No signs of smoke, starts easily. I do have to prime it while it is running for about 30 seconds after a cold start.
That is one scuzzy carburetor donyboy73,looks like you are taking the easy way out,LOL.
very good job well told how to fix carb thanks
I have the same model in this video. I've used your videos to take everything down, clean, and re-assemble. I have one problem that stumps me. When it starts running the rpm is so low it can barley cut light grass and runs ruff. As the gas tank runs empty the rpm picks up considerably for about 30 seconds until the gas runs out. It seems like maybe its running too rich but I don't see any adjustment for that. Any ideas you might have would be greatly appreciated.
Great videos donyboy Thank you so much
Thanks a lot. Nice video, well explained, good images and well putted together.
I love THE 2 stroke sound. Good vid
Hi, After watching your video I was able to remove and clean the Lawn boy carburetor and it fixed my surging problem. I only have one question regarding the plastic sail. My spring became detached when I removed the carb and there appears to be 2 places where it might be reattached. There is a little plastic nib on the carb housing that might be an attachment point or there are other plastic parts that swing back and forth with the sail that may hit the spring if it is just left to hang free. Could you tell how to attach the spring on the sail? Thanks for all of your useful videos.
two stroke engine lawnmower, with plastic carb,never seen this one before,??good vid,
very reliable and somple
two stroke engine lawnmower, with plastic carb,never seen this one before,??good vid, cork float??new to me,??
Thanks for the explanation
Thanks for the video. I found one of these on the side of the road today with a free sign on it. It had sat out in the rain for i think at least a year or two. I was bored so I took it home to see if i could get it running. Cleaned the carb and removed about 3 lbs of oily mud off it. The recoil is still super loose on it but I got it fire up and run. No smoke, runs good. I think it was manufactured in 1988.
Any advice or videos on how to reload the spring on these? Thanks Dony
Very clear and well done. thank you!
Great vid, I learned a lot about this. question, on my 8237 LB, I serviced the carb, which had bad gas. The high and low rpm selector doenst really do anything, like its stuck in low. @ things I noticed, Crank is wet underneath, so need new seal, and primer hose is hard. do you think those two are the culprit? This is my first LB experience, also I checked the wind gov. it's not set too low. Any Ideas would be much appreciated.
Thanks
Hi Donboy, I do have a lawn boy 19 inches just like the one you cleaned the carburator. I did all you demonstrated but I still have to supply gaz/oil in the hole of carburator with a spray bottle to keep motor running and when I stop feeding, motor stop immediatly. Gaz valve is open, gaz comes into the bowl . Any idea to help?
Last fall i rebuilt a carb in a Toro CCR 2450, and the carb on the Lawnboy looks very similar.
This was a very good video. Thank you for posting it.
TheSwampfoxOutdoors thanks
Thank you!! easy fix, lawnmower works now!
hey donyboy. i followed your instuction which are great by the way. My problem is fuel leaking out as the lawn mower sits. I cant see any problem with the fuel lines and I shut the supply off after im finished. Any thoughts?
Thanks for the video, i tried to clean the carburator but my problem is when it’s a cold day like today (2 celcius) i can’t start my lawn boy. Do tou have any idea ?!
thanks good job
Thanks Donboy.. I have an old 5022 Model and I needed to see how to try and fix the needle and floater, don't think needle is working right to stop the gas flow and it's over flowing the carb.
I have a 1979 Lawn Boy Model 5124 Engine D409. I see only 1 adjustment screw on the side of the carb. Someone told me its the altitude adjustment. If I screw it all the way in how many turns out should I set it? I also hooked up a tachometer to see what the RPMs is running at and im getting 2250 RPM on idle is that normal? Will the RPM change once I start cutting grass? Thank You!
hey i was wondering when should you clean the carb and my fuel shut off value will not shut off should i buy one that plugs on to the hose
nicely done video too! easy to watch.
That lawn boy looks like my friends mower he bought it new 1989 so is this the same model and year as a 1989 and he has no compression or very low . He said
it has never been run without oil in the gas . Can you show a video on how to rebuild the engine and I will give him the link to the videos. I will also give him this link so he can check the carb. Once again your a great mechanic.
Thanks for posting this was great help!
Excellent video. Thanks.
thank you for all the videos
who makes the lawnboy??
I NEVER knew that there were supposed to be plastic plugs on the screw access holes! I bet they get lost a lot any time the carburetors got cleaned! Maybe now I can teach you something: you don't have to tear apart the filter screen to get at the jet, it pulls off the bottom if you pull hard enough. But you probably figured that out since then. Cheers.
Awesomne video. Such a rarity. Please tell me what camcorder did you use?
Hi Don, I have a lawnboy 10401 that hasn't been used much since new but has been sitting in storage for at least 4 years. I changed the plug today and put new gas but it won't start at all (after close to 100 attempts at pulling the cord and priming it) . Any suggestions on what I should do first?
@donyboy73 just took mine apart and the needle shown at 2:21 is stuck inside the screw mechanism can i buy this at a small engine shop too? will it need adjustment?
@Liamautomechanic yes it's about 15-20 years old and all plastic carb
hi donyboy. Is there anyway of adjusting the float to stop the fuel from pissing out the carb after you shut down?
@donyboy73 thanks ill look for one couldnt get it out (its corroded from being filled with water) but everything else seems to be in good condition
i love my lawn boy there so nice
Cool video man ! and was that whole carburetor plastic ?
great vid thank you , keep them coming
@flhebhammer thanks for replying it has the carburetor that is affixed to the air cleaner is all one pc and the throttle cable attaches to a sm bracket held on by 2 screws inside the air cleaner body, model # is 10314,the parts diagram shows the parts but not what the end of the gov spring attaches to. thanks, neil in fl
Thank you
times like this i miss my victa mower....that started 1st pull
Great video! Do you have any plans on making a video showing how to replace the air vane governor spring. I have on that is giving me fits.
Do you run 32:1 or 50:1? What octane do you use?
Its okay until next year? im using this mower for my cutting business and I don't have auto until next year should it be fine until then?
Very helpful... Thanks!
I have a lawn boy 8237 and the only way it will stay running when cold is if I keep pushing the primer until it's warmed up. It has good compression great spark clean fresh fuel please help
dony, what causes a briggs/Stratton to surge after about 30 minutes of running, I replaced spark coil, and it does the same thing, any ideas? thanks...
Dony, Cleaned the carb numerous times. Engine starts then stalls. At my witts end with this. Its a lawn boy 4600 model. same exact carb. Reed valves look good. any ideas?
blow the gas line with air
@outdoorsman310 try to gently pull it out, i think u can still get them, i may have a used one here
Hi Dony,
Could you make a video on setting the dual speed mechanism properly. Mine's (1975 8252 model with D-481 engine) is stucked on low speed. Merci beaucoup !
Daniel Robert
Hell, The reservoir of my lanw-boy 10247 silver pro mower is leaking when my mower is on and when it is off. It's leaking under the carburetor. The lid seems to be tight with the gasket. I don't see a crack. What can I do to correct the problem?
Thank you - I will try on the next couple days and find out - have a great weekend...√
Thanks! Mine was leaking all my fluid and it turned out it was my plunger coming off.
good job
do you like that the carb is plastic or metal
@Liamautomechanic actually the same company made outboard motors, OMC i believe it is
@ncrdisabled i never get one to rebuild because it is too expensive. i doubt the parts would still be available
Great video does the 8241 ae have the same carb cuz seems easy enough I could do it.
thanks! great video
EXCELLENT video.
thanks for subscribing
And it has a bunch of blue smoke coming out of it while im cutting grass, is that too much gas not enough oil?
Donyboy is such a cutie pie
I really need ur help with my lawn boy, the throttle on it is broken and it wont start can u show me how to fix it plz
