How to Diagnose and Repair a Small Engine

This video shows the general process I use to diagnose and repair small engines, like the ones on string trimmers and chain saws. It's not that difficult, and doing it yourself will save a LOT of money!

This was a great quick take on small engine repair!

Im seeking to learn how to repair small engines. This is the very first video I watched on the subject and I am extremely pleased that I started with this video. I learned a whole lot. You did an awesome job. Thanks

Fuel, compression, spark. Even I can remember that.... I love how you break it down to its basic parts.

Nothing makes me more money than people claiming they know what they are doing who don't. Then to have them teach others! WOW! Keep on keeping on!

Great video! I'm retired but stay busy. The lawnmower shop in town asked me if I would repair all the 2 cycle engines that come in, I'm not exactly new to doing this but this was great refresher course for me. You know your stuff young man, keep up the great work! Thanks!

I like that you have the patience to teach. Good job.

The good way of small engine diagnoses, I love this video, thank you so much for taking the time and explaining things. I am a fan.

Oh isn't that nice how the older motors have simple adjustments!! Nice video!! You go at just the right speed for people to learn...👍👍

Unbelievable... So it just needed fuel but you still went through all the troubleshooting for teaching purposes? THANK YOU

Over the years I have found that 19 out of 20 problems are fuel...people use regular gasoline in their portable tools & it has ethanol which destroys the carburetor plastics & goes stale to create varnish when left. I always use Shell premium grade fuel (zero ethanol), empty the tank out & run my stuff dry when I am going to store it for more than a month or two. Never had a single problem with anything since I started doing this about 15 years ago...

Just got promoted to assistant maintenance manager, this is a large part of my new responsibilities, thank you very much

Thanks for the video!! I was searching for general information for small engines with zero previous knowledge, and this is exactly what I was looking for. Now I just need to get my snow blower started.

[michellenella]

Oh my gosh!! Thank you for your step by step review of a small engine. Im new, newer than new. The way you described in details stepby step…I can fo it. I boughta stepby step book but your video was great. Now, to wait for my husband to go into work, then….to grab the leaf blower!!! I can do this. Thank you. Fantastic.

FACTS - Fuel, Air, Compression, Timing, Spark. Most people only know, acknowledge or remember three of those (and not even the same three, as seen in this video) but all five are required and that acronym is easy to remember and really makes for more complete troubleshooting.

this man made this old clunky two stroker work. Thumbs up!

[donaldbronikowski]

I work at a hardware store repairing equipment and I can relate to so much of this. What really hit home is the part about asking the customer questions to get an idea what's wrong wrong with their stuff. The problem we have is the guys in the store who actually talk to the customer and write up the work invoice doesn't ask many questions or doesn't even know what to ask. You have to be part mind reader and part detective. And being lucky doesn't hurt

I just want to say thank you for sharing and for being so detailed in everything.

Knowledge is power and those who share knowledge empower others.

Absolutely Loved this video. I am an Auto Body Painter and painting for 42 years, and getting tired of it. But I have NEVER tried to fix or even mess with small engines. But now, I am going to. Thanks to you. Gave you a thumbs up and subscribed as well.

Very fine tutorial! I've got a (Ugh!) Harbor Freight Predator 52cc power auger that just won't start. It's about six years old and started to stall after running a couple of minutes when I used it last year. I threw it in the storage shed over winter and didn't drain the gasoline but did add stabilizer. I recently decided to see what the problems were. The fuel lines were deteriorated and the fuel filter was rusty and semi-clogged, so replaced those. Put in a new spark plug and replaced the old carb with a new one ($16 @ Amazon). Cleaned fuel tank and added Start/Conditioner/Cleaner fuel. Replaced the air filter. And it still won't start. FRUSTRATING! I'll try the spark plug check you recommended to see if it's actually getting ignition because that's all that I can think of. Maybe it's time for the junk heap and moving to the newer Ryobi 40v electric auger but I'd hate to do that as i Have three different sized augers for the Predator, which, of course, don't fit the Ryobi shaft diameter.

Fantastic video!! Should be required viewing by every American.

If you do nothing else in your life (which I doubt) this service you've provided here is enough to earn you a spot in Heaven. Thanks.
