Easy to follow and thorough step by step video 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 KZread and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!

This video, and another I found specific for a 196 CC Honda clone, really helped me swap out a 5/8" shaft to a 3/4" for the addition of a torque converter on my minibike. Thanks!
The video makes it look so easy. And it was! I've grown to love small engines. Cheap education and entertainment.
Air hammer tip is great, it has so many uses we tend to forget, great!
EXCELLENT VIDEO. One of the best detailed videos I've seen for removal and replacement of crank shaft. Thanks. I think I can do it now!
Well done and even though there is no crankshaft swap in my future, I watched the video anyway just because I like the way you do them.
Three excellent skills; mechanical excellence, video presentation excellence, and teaching excellence. Thanks.
Using the air tool to loosen the flywheel was a valuable tip. I always learn something from these videos. Thanks for posting them.
Keep in mind, I missed this during rebuild of a 1980 3.5hp Briggs vertical shaft, the crankcase gasket, there are two for this engine, this one needed the .015. I could barely pull the engine through, broke in all back down miked everything put it back together and still was so stiff, I did get it to start. but pulling it through was just too hard to do and I knew there was something else that needed my attention. The dealer had sold me a .005. I didn't give it a second thought, until I remembered reading about the two different thicknesses. What a difference a few thousands of an inch make. Great channel.
Very helpful step-by-step instructions. Original engine with old style starter clutch and all metal parts was nice to see.
Excellent video! Left absolutely no questions! Perfect and thank you.
Was in a hurry one day putting new rings in a Briggs and didn't emery the crankshaft before reinstalling the sump! I thought how bad can it leak? It didn't leak much, just enough to run down on the drive plate on a Snapper rider! Had to stop cutting and clean the plate every 20 min from then on! Live and learn!!
Thanks you so much for putting these videos up. I successfully rebuild a honda gx 160 thanks to some of your vids. By the way I am from AUS.
Thank you for this great video. I especially appreciated the efficient presentation and concise editing. Well done!
I enjoyed watching you change out the crankshafts on the two engines and believe that I could do that. I need to figure out how to get my power generator going which have not been started in many years. It never was used since I had problems with it since buying it, and installing the oil in it. The newest one worked fine, but I never used it since our power never stayed off long, when we lost electricity.
Well timed video. I'm just about to swap out crankshafts from two similar Briggs and Stratton Motors. Thank you sir.
Very nice and helpful video. I had to replace my crankshaft in the same motor as that one, but crankshaft was slightly different. Thanks Dony:)
I love the videos very cool learning how these work!
Don..you are awesome. You are a life saver. Thanks for your videos..
Enjoyed this great video and, as always, learned some excellent tips.Thanks
It won't be long and you'll be in the 100K club Donny! Congratulations on your channels success! Also, great video as always! Cheers!! Zip~

Hi Bruce! :) lol!
Wow, excellent job my friend!! One of the most informative, concise videos I have ever seen. I wish you could help me with 1 year old Briggs and Stratton with a bent (I think) Crankshaft. I found out you can not cut a 3/4" reinforcing rod with a Lawnmower. LOL!! It was hidden below some weeds I was trimming. Should have used the weed wacker, now I know that. I did replace the Flywheel keyway and the Blade, now it starts. It runs fairly well at full speed but at idle it vibrates like crazy. Oh well, you live and learn.

I usually do not end up repairing bent cranks
great video , like to see more of these repairs.
excellent video, great photography & edits. Sometimes it may be better to search for a used engine with the right crankshaft. Thanks
Excelent video very useful
Thank you nice job,
Nicely done
Ok!!! Now that was amazing.
Another great video. Holey moley, nearly 100,000 subs!!!
Nice job.

YeSir.u.The.Man... big thumbs up...

Brilliant thank you

Welp. Now I know how to do my vertical shaft 8hp B&S. Thank God it's easier than I thought. The things I do to restore an old mower keeping as much original as possible...
great stuff!
GREAT CLIP
thank you.
very nice job.
Thank you....Well Done Video....
nice video thank you.
Some things I liked.
Great video! Love the way you walk through everything. What is your parts washer, and what do you reccomend for someone who would be looking?
Cracking video.
Good video
Hi Don, thanks for making this video! You are a great teacher. I have a question: what were the torque specs for the bolt on the flywheel? Thank you!!
Excellent video! I am working on a motor with bearings on the crankshaft and I was wondering how to match up the timing marks
thanks for this ...

Well done son..your a great mechanic and your videos are succinct and easy to follow. Have a question..Honda GVC 160 sheared the key drive sprocket for the timing belt. Have you ever seen that before? Again...great videos..keep up the good work. Jack in the Republic of Panama
Do you remeber what the torque setting is for the flywheel nut? Thanks! Great video, very helpful!
EXELENTE !
Hey Don, Great video. Exceptional step by step instruction and great camera work. Just wondering why since I don't see a single video on YT on reworking a head on a riding mower with briggs engine. I see them on the small engines where the valves are lapped but nothing on the riding mowers with the overhead valves. Just wondering if new springs, guides and valves and guides can be put in or would it require machinist work and make it more cost effective to order a new head. I'm sure that would be a huge cost though. Anyways would appreciate if you would comment or make a video on that. Thanks for your great channel !
On the engine you were running at the end (the five hp b and s) I am currently working on one and wondering if you could make a video on how the governor linkages are set up on this particular engine because I have done research and cannot find a diagram for the engine
Guess I will pull the bent crankshaft on my Honda mower. I was going to try and get it straightened but for the price, Its just as easy for me to Replace instead of messing with a bent shaft.

yes sometimes, just find a good used one
I need to do this to my pressure washer, will it be about the same way as you did here?
do you think you should torque twice? in my experience the bolt always moves a little tighter the second time.
Sweet you did video on the rewind on new one?
Is there an adaptation to convert straight to taper shaft?
Can these bolts on the sump cover be different on a different motor because mine are 7/16
Hi Donyboy, Always enjoy your superb videos. Just an FYI, I took a keyed crankshaft from an 8hp Tecumseh snowblower (that had a broken rod and cracks in the block) and put it into a 10hp Tecumseh wood chipper engine that had a tapered crankshaft. I checked all the specs with my micrometer and everything was exactly the same. The only difference, other than the crankshaft end, between the two engines was the piston bore. I used my "new" snowblower with it's 10hp engine for 3 hours after a big snowstorm and it worked just fine.
@donyboy73 , Is swapping a sump cover from another engine ever a problem due to the block being line bored for the crankshaft during manufacturing, thus pairing the engine block with it's own specific sump cover? Also, any need to check crank endplay after that swap?
Nice job. All you need now is a mini bike frame and some wheels.
I have never tried that "Ultra-Black" stuff. I've always preferred "TABER'S" (IF one can find any), Or Permatex "Form-a-gasket".
hi donyboy, i have a question for you about a small engine briggs and stratton sn 128m02/0134f1 the engine was blown, prob was the connecting rod. i did replaced it with the right match, however when i tighten the bolt ,100inch lbs and tried to spin the crank shaft it won't turn at all.
Best video of small engines to date. I have a 5hp B&S horizontal engine on a go cart. I replaced the carb. It's back together but I can't get the throttle right. I can't find a schematic of this type. No manual throttle capability only the choke. I need a choke rod so could use some advice how toi find one vs making one. The governor is functioning. This go cart engine didn't have the race track in the linkage which interacts with the manual throttle control. I know linkages vary and the model # for this one is no where to be found. I just need an image or schematic reference of how this should connect. The new carb came with the throttle on the carb hooked up. Also, the needle valve for mixture control did not have a spring on it so I'm guessing I use the old one even though the new needle valve looks different than the old one and the ones in the kit. Hope you can help advise about a schematic or and image or two of how this throttle linkage should hook up.
Blew up a 1100$ Briggs world formula, I guess I’m gonna rebuild it. Just need to get parts. I need a new crankshaft and a connecting rod. And a clutch.
I have the same situation with a Honda Gx390. It has a long taper and I want to replace it with a keyway shaft. Do you think it will fit ?
Hello. Craftsman engine model 20M314 what torque on the crankshaft cover swamps?
How universal are engine parts from year to year? Where do you get your parts for older / newer engines?
What size impact driver do you recommend for small engine work. There are so many of them out there it's really confusing. I know you require special sockets with an impact wrench. I would prefer something battery driven or electric rather than an air tool. My use is for my own equipment, no commercial work. So basically it would be used on lawnmowers, my riding mower and generator. Thanks Dony, appreciate your help!

Dony i have a question for you. Do Canadians, or for that matter people in your community have a tendency to purchase quality outdoor power equipment? Here in the States most people buy "one season wonder" throw away equipment. I'm curious as to your opinion as a Canadian. Maybe you can squeeze this onto a q&a video...? Thanks. Longtime subscriber here.
Mineral spirits kicks ass...
Dont forget to tab over the bolts on the bottom of the crank shaft otherwise very informative thank you for a great video
Ok. I have a Honda GX270 9hp small engine that has a short crankshaft. What can I do to extend the shaft please?
I know your application didn't need the bearing but if you did need it, how do you remove the crankshaft bearing ?
Hey man, I need a crank for a 7hp Briggs. I can't seem to find much on 7hp. 6hp and 8hp. But not much about the 7hp. Can I use a crank from anything else? Thanks
