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"!
I want "DON THE SMALL ENGINE DOCTOR" on UA-cam to save you time, frustration and most importantly, MONEY with my HOW-TO videos!

thanks for the info. this helped out really goood.
I'm a simple person. I love listening to and watching small engines run. It's very satisfying to see and engine running after not starting for after a year and a half. I experienced a similar scenario after your videos helped me to get an 18-year-old gas trimmer going that had not started for three years.
Absolutely great video. Replaced the carb on my 23 year old Murray with a B&S 14.5 motor.
Couldn't have been easier. Thank you!
Exce!!ent instructions and video! I really needed that information since I am replacing the carb on my old (22 years) 42" Craftsman mower. I'm 82 years old and getting forgetful 😊. Thank you!!
Your video is so clear that it make me impatient to replace my carburetaor .
Bravo !
+Ma Pa lol
Got a free Craftsman LT1000. It had been sitting outdoors for at least five years.
Both the rear tires were flat... Replaced the carburetor for $89, Rear tire tubes for $26 and the blades for $32 and later the mower deck belt for $16, air filter $14, oil change $4, cup holder $5. It runs great and has earned its keep already this summer.
You can't appreciate a lawn tractor until you've spent 30 years pushing a mower....
Beautifully done video. I'm dreading replacing a carburetor on my old Bolens, so this was very timely for me.
Every time i watch your videos i want to run out and start working on one. But since it is about 11pm here, i think i will wait. Thanks for another good one.
Great video. I was wondering where all of those small plastic pieces that came with the new carb went. I have been searching for days. The way you explained the choke process, Great video.
You make my day... I clean my carburetor, put it back in place, and the engine never work so well!-)
Great vid!!! I kept scrolling on other vids that took me nowhere but this one was right on point. Thanks for doing this for people!
I work on mowers in my spare time here in texas and 2 times last year I had customers said motor ran at way to high r.p.m. well I found the screws fell out of the butterfly for throttle and of course the screws on one got imbedded in head butterfly did not make it past valve the other butterfly broke in half never found it and 1 screw have you ran into this problem thanks for all the time you put into teaching everyone how to repair the machines
Thanks so much for this video! I'm doing this, this weekend along with adjusting the valves and changing the oil.
Excellent Video with step by step instructions. I found that the choke control lever was a little different that the original. There was a small plastic vertical knob that interfered with the air filter housing. I simply cut the little knob to make it like the original carb. Don't forget to attach the solenoid cable to to the bottom of the Carburetor. my 14.5 hp engine has never run better.
Excellent vid, I replaced the carb on my briggs 12.5 flathead a couple years ago and it fixed a surging problem the engine had
Never changed a carb on one of these things. Epic video! Explains it perfectly! I appreciate it! Subscribed to your channel 🤘🏻
Hey Donyboy, I applied this video to my Murray 17hp Tecumseh engine, and it worked out beautifully. I appreciate your help! Thanks
you're welcome
One of the best-presented and useful instructional videos. Many thanks.
hey brother you are the best. you just helped me alot, am helping a buddy of mine fix lawn mower, so this was very helpful brother thank you so much.
So freaking helpful. Only complaint is I didn't find your video sooner. Well done.
thanks Walter, make sure you're subscribed
Thanks Donyboy, you made a great job, very helpful.
Nice video - I have a slightly different carb - 593432 for a Snapper RideOn - but this was still a help and love that it is high quality video.
Thanks brother, I found part cheap on Amazon with your help. It's on it's way. Thanks again
I've been looking and looking for this info! Good quality, easy to understand video. Thank you very much.
you're welcome dude, just in time for spring repairs
Partstree had it in stock. THANKS for your assistance.
dony - Great video - just bought a Craftsmen 15.5 HP 42" Lawnmower Tractor. This thing has not been used in a couple of years I think. I am ignorant when it comes to this kind of stuff. Am now retired so am going to have to learn. Your video is very good with the exception of sometimes the attention to detail in camera work and instructions for us administrative types is lacking, but it is the best I have found yet on You Tube. Try to focus in on the links, springs, etc. Watch your fingers
Thank you so much for posting this video it was very helpful.😀😀
God bless you always donyboy you are a good person you help millions of people.thanks again
thanks
Thanks for your videos. They are clear and understandable. I now have a mover that is running like new. Its 12 years old Thank Again
you're welcome
Great video Donyboy. Very helpful. Thanks.
You’re the man! Thanks so much for saving precious time
Very well done! Easy to follow and understand. Thank you!
reat video, sat laptop on my workbench while replacing my carb. Great presentation and great explanations. the former carb was flooding out the engine. With new carb on it ran, but smoked like crazy. I figured the exhaust was full of oil and gas from the former flooding so went and cut grass for 40 minutes. It eventually cleared up mostly, but not all. I am wondering why it would now smoke and if it could be the valves? I had lockup on start and found a video on setting the valves and that solved the starting issue, but why would it now smoke?
always improving, thanks for watching
Dony, once again an excellent video! very helpful! very easy to follow! clear steady video, no camera shake! the best on you tube! Danny would you be able to show us how to clean this carb, and maybe rebuild it? Cleaning would be great because I have to do mine very soon, and the engine and carb look almost exactly as this one. I followed your other video where the engine is in the vise. very good, but the carb is not exactly as this one. and I don't want to miss cleaning any hole or orifice. Thanks Dany And have you done a video on cleaning and tuning up a big brigs flow jet on a horizontal shaft engine like a 12 hp.? as I could use that video also soon! Thanks again.
Excellent video! Thanks. Exactly what I needed.
Very useful, thanks Donyboy - the video is also a very good quality.
I came here to see how the governor cable and spring hooks up to the throttle butterfly lever. I am reinstalling my carb (after a strip, clean and paint of the entire tractor) and the throttle stays open all the way - just with more or less tension according to the plastic slider position that is controlled by the throttle cable. Is this right or should the governor close the throttle when the throttle cable is pushed to the idle position?
Thanks for the video and the details which I would have found very useful when I had the smaller 3.5 HP engined grass cutter.
Great video Don. As usual!!
This was exactly what I needed. I feel confident enough to repair my carburetor on my own now. Thanks so much!
Great video, Dony!! Very informative! (As usual). God bless you both. John
You are so good teaching God bless you e.g...you help me a lot with your videos thank you very much
Thanks Eddie. I had thought of JBW but not with a coat hanger. I may try it if I can think of a way to support the hanger while it is drying. Maybe I could leave the carb on the engine (drying position would be horizontal) and set the hanger on a wood block laid at the bottom of the engine compartment. Another way might be to remove the carb and lay it on its side on my workbench and just hold the hanger in place for however many minutes it takes for the JBW to firm up enough to hold it.
Very helpful! Thanks for sharing your knowledge!
Very informative video! Thanks for sharing it.
Love this video. My grandma's lawn tractor wont stay running unless the choke is closed but eventually sputters out anyways after a few minutes. Should I just do this and replace the carb?
So well done and clear and helpful. Thank you!!!
Glad it was helpful!
The filter on that mower is made for systems with a fuel pump. I guess it has been working fine. Always wondered what difference it makes.
Great job!!! I'm going to try this!!!
Good job! I do those all the time.
thanks for the video extremely helpful!!!
I have a JD 155c that I want to do this too, but instead of replacing the carb, I want to perform maintenance. Do you have any videos that show how to do that? Will be checking in a sec.
Donny you're awesome! I appreciate you
Thanks for great video. I have fuel 'standing' in the carb throat. I paper toweled it out and tried to start,but it starts then stops like running out of gas. Is float stuck?
Is that type of carb not rebuildable? Is it not necessary to put some locktite on all the bolts you are putting back? Nice video!! Thanks for sharing your talent.
Will try them. Thanks
Thank you!!! Runs great now.
Do you have any videos for the Kohler Command 14 Pro Series engines used on John Deere and Scotts 42" lawn tractors? General Maintenance, oil change, carb service , etc.?
Hi, I have a Huskee Supreme 25.0HP 50 in. deck from Tractor Supply, probably almost 8 years old. Almost put in the amount of money that was paid for it in repairs to the local small engine repair store. So, this year, I am determined to get this thing running myself. I am having trouble finding a video of the carburetor cleaning/repair of a similar model. I put in a new battery, fuel filter, oil filter, air filter, spark plugs, oil change, new ethanol-free gas, even pulled out a mummified mouse. From what I have read online, I figured the carburetor is next. It still won't start, even when I sprayed ether in the intake...Don't know where to go from here. Thanks for your help/advice.
Another Great Job, Thank you!!!
was just wondering . i changed my carb as directed and one question came to mind. when you put the two tubes back into the fuel tank , how much of the return tube should be inserted into tank? My tank was 1/2 full but the return tube didn' t reach down into the fuel. does it supposed to reach all the way down like the other tube does? I did notice that the primer didn't work well so I filled the tank up to full and noticed the primer worked much better and everything was fine afterwards . thanks for any comment you have on this .
Id take a marker and put a line on each side of the choke cable bracket before I'd remove it just so I'd know where to put it back...great video
Fascinating. Great camera work.
Question:
where I connect the black wire that comes from the solenoid?
Please help!
Don I followed your video very closely, the new carb went on great. Lawnmower started right up, but keeps surging. when i put the throttle to low it runs smooth, but when I try to get some speed it starts to surge and then quits. What can I do to get this running better? Thanks for the video and help.
This was a good explanation,thanks!🇩🇰👍
Symptoms of why part/carb needed to be replaced ( for example bad solenoid )? Great Vid Doc!
Great detail on this video as always on your great site. Thank you!
Glad you enjoyed it!
Great video, I have 2 questions:
1) how long did the replacement take?
2) when you work on machines, do you do any clean up? like power wash?
Smashing tutorial as allways :-)
So nice to fit new parts that you know are spot on :-)
Thanks for a great Video DonyBoy
you're welcome
Nice vidoe Dony!
Great video dony, as always. :)
Any tips for adjusting the carburetor ?what position should the adjustment screw be in . what is suppose to happen whenever it’s turned in or turned out . I’m experiencing engine surging in the fast throttle speed setting .Idle speed runs fine and motor starts well . Any suggestions are appreciated
if you're mechanically inclined you can replace the needle valve and seat, may save you a new carb purchase
Dony I have a carb prob. Same as the one u did in this vid. It has a different solenoid on the bottom of the bowl. It was leaking so I tightened the solenoid and it broke. Can I replace the solinoid or do I have to replace the carb???
Before I replace the new carburetor on the engine could I copy the adjustment screw that's on the old carburetor so that I don't have to do any adjustments once I start the engine?
I am in need of help. How do you install a "switch stop"? I'd really appreciate it, thank you.
Thanx for answering, and your video`s are helpful!
I have been needing to find a video about how to replace the carburetor on a 1998 Murray with a 17hp Tecumseh engine. This carburetor looks like the one I am replacing. I hope it works. The only difference seems to be that my breather cover has two screws instead of just one.
Did you adjust the idle screw any? I just bought a new carb for a B/S 175cc Professional series engine. Are they factory preset? Is there anything I should be aware of before starting? You make everything look easy. Always enjoy your vids.
Will the connector on bottom of carb work either way? I forgot Wich way it cam off and it goes on both ways.
Dony do you know what size bolt is used to hold the blade onto a briggs and stratton 35 classic engine?
Your videos are an inspiration many Thanks.
I have the same question as Kirbywatch07. How do you remove the bowl? On my carb, there is a sensor on the bottom of the bowl where the nut should be.
Nice job once again. I found that using a heat gun to soften the gas line helps it to come off very easily. This is especially good when you have a short line that you need to reuse.
Nice video , I was working on a similar engine today on a tractor that has been sitting for years, emptied the old gas out and still wouldn't start i will use your video as a guide to clean the carburetor, do you think it is all gummed up?
thanks joseph
I enjoy your channel. Thanks.
how many turns out do you need to set the mixture screw
At 3:37 Where could I get one of those adjustment screws? I was working on my tractor that has a 2010 B&S 12.5 Hp Power Built engine and I went to adjust that screw I broke it right off, I managed to get the old screw out but I can't find a new one.
Hi Dony, I have same model 17hp and locks up when turning over. I have to manually turn back the crank to the end of the compression stroke so it can get a run at it. Most times it won't turn over passed the compression stroke. I adjusted the valves like your videos. Does that model have a compression release built into the exhaust cam?
Local mower shop suggested I Polish the seat because they did not have one
Do you think I should replace it ? I do have the replacement needle valve
The po of my mower broke the tip of the mixture screw off inside the carb and wont come out. Any tips on hot to get it out?
thanks,........ will do this weekend.
hoooooo wheeeeeeee! a GENUINE carb. that mustve costed a fortune. lol( i always rebuild or use aftermarket)
your vids are always packed with information. keep them coming😊
larry johnson
go onto amazon. youd need the make of the equipment it is installed on but just typing in walbro 4993 carburetor comes up with multiple listings. as cheap as 15 dollars. find the one with FREE shipping and make sure it is a us seller unless you want to wait a month lol. if you have prime shipping from amazon is free. 30 day trial is offered IF you never had prime in a year or two.
my carb. for my snowblower tecumseh hm100 engine has the fuel fitting angled compared to straight i know they can be swapped but i didnt bother. rebuilt that one. kits are dirt cheap as well.
larry johnson
lol well as the saying goes....try try again. i pulled up suggestions around 13 dollars cheapest. youd need to get the carb numbers and engine info. it sometimes takes me hours but its there.
also try ebay.
I accidently broke the idel adjustment screw such that the threaded end is still in the carb (same one as in this video). I can't get pliers on it in order to remove & replace it. I have run the tractor a few times since & it still idles fine as before I broke the screw. I guess I could get the broken screw out with a screw extractor but risk damaging the carb. Do you have a suggestion? Thanks.
I have a 14.5 HP B&S 287707. It has a Nikki carb. I cleaned it with berrryman carb dip and blew it out with air. I did however re-use the gaskets and needle. Basically i cleaned it and put it back together. I reinstall it on engine, and the engine starts on full choke and will run at full choke for about 10 seconds before dieing. Also, as soon as I pull the throttle lever down in those 10 seconds, it immediately dies. Any suggestions? I thoroughly enjoy your videos and have helped tremendously
210000 BS intek Has done this since it was new off and on, load tested battery did a starter draw test, cables even went directly to the starter with a good battery.Sometimes it works ok but most of the times it does not. I was told by a dealer early on that there is a sliding compression release built into the exhaust cam lobe and I was wondering if Dony had run into this problem. Compression test was within specs at the time according to dealer.
dony boy i have a 2008 1705 overhead valve briggs on my troy built pony it was surging because the adjustment screw fell of i thought it was the carb so i tore my carb apart and it was a nikki so i got a new one and it runs good choked it doesn't have a cap on that screw for mixture adjustment and the engine surges when ever i try to give it full throttle please help
