I have 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 whacker, 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 KZfaq and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!
I want "DON THE SMALL ENGINE DOCTOR" on KZfaq to save you time, frustration and most importantly, MONEY with my HOW-TO videos!

I like the tip of leaving the throttle handle assembly held together with screws. I don’t know why I didn’t realize this, but every time I’ve worked on a clutch, I’ve taken the handle apart all the way and then have more work trying to get it all back together.

Hello Don. I just want to start by saying I always enjoy watching your videos on small engines and have always appreciated the way you present your videos. With my limited knowledge of small engines I learn things all the time from your videos. I enjoyed this video how to fix a Stihl trimmer that has a head that will not stop turning but I wanted to ask your opinion as to what trimmer(s) you might confidently suggest for a homeowner who regularly weeds around the yard on a weekly basis? My trimmer which is more than 15 years old is starting to give up on me so I am going to seriously start looking for a new trimmer. I really appreciate anything you could suggest. FYI, I also sent a similar comment to Chickanic and Steve's Small Engine Saloon. I really respect the opinion for all three of you.

Honestly my customers stuff I always give the greasy areas like the carb and such a brake clean and air blow. Then wipe down the plastics the worst thing when a customer has a bad day they spend money and it looks exactly the same as they dropped it off its kinda a feel good thing for both people and most of the reactions are worth it. Also I got yelled at one time for straightening out someone's handle. Since that trimmer has no guard I often do scenarios where I go into my junk pile find a much cleaner or that missing little part and say look I'll toss this on they are normally say 30$ I'll toss it on for 20 installed. That way machines look presentable and you got added money from your junk pile. Awesome work though.

You mentioned putting some lube on the shoe arms, I guess at the pivot point, but I didn't see you do it. The clutch is working good now, so I guess it didn't matter. I don't have any Stihl equipment, but it's always interesting watching your repairs. I do as much for myself as I can and I always learn something from you. My Troy-Bilt Powerhead likely has something similar. It's not a all-in-one like that one, but takes attachments, of which I have a few. Thanks

Hi Don, for the 2 swinging clutch shoes, if I need to put lubricant, should we use anti-seize or di-electric grease (i know this isn't electrical but i found di-electric is a super good lube to install things etc...)? Re-assemble looks way more tricky than dis-assemble, only someone at your skill can accomplish, amazing work Sir ! 👏

Graphite lube is better, it is dry. Sometimes I just put a very thin film of anti-seize where the hinge is on shoes
