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 chainsaws, weed eaters, weed wackers, string trimmers, grass trimmers, line trimmers, hedge trimmers, strimmers, brush cutters, leaf blowers, or four stroke, four cycle units like lawn mowers, lawn tractors, snowblowers, pressure washers, generators, ride on mowers that need parts installed or replaced, I’m your goto 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 Youtube and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!

I want "DON THE SMALL ENGINE DOCTOR" on Youtube to save you time, frustration and most importantly, MONEY with my HOWTO videos!
