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.

You have no idea how much this video helped me. I have no electricity in my home. My generator broke down. My kids need fans to keep out the mosquitoes and to charge their computers for school. I was struggling in the dark trying to fix this. I watched your video and got the solution. Thank you brother, wherever you are.

[MrVegasTube]

As a gen owner I appreciate your diy fixes. Very well presented for us willing to do the work.

Five hundred and eighty-three thousand videos later I found this video well explained and with a good solution.
Thanks.

I wanted to express my appreciation for your video on diagnosing an ignition module. I followed your suggestions and had to replace the module on a 30 year old Honda lawn mower. It now cranks on the first pull after replacing with a new Chinese module that I ordered on line for a little over $20.00. Regards, Greer

Thank you for this video. You are the reason I fixed my work generator. Tried everything I could think off and found my ignition module badly misaligned, almost sideways and rubbing crank wheel with other corner. Got a business card and made it right like you said. Now it starts at first pull everytime!.

[tomhrkach]

Wish that I had checked out your video before I frustrated myself trying to figure out my issue. Thanks so much! Ordered the part from Amazon ($27), followed your very clear instructions, and lo and behold it started right up. I almost jumped for joy. Keep up the good work! 💪

[razijun]

Two thumbs up. You are a brilliant teacher, I wish I had a great teacher like you, when I went to school.

[jeffschulken]

Had a no spark problem with my Predator 3500. After checking the usual no spark issues I found your video. Ordered a ignition control module/lighter from Harbor Freight parts. $25 later and my generator is up and running again. Can't thank you enough!

This man knows his stuff, take note and you won't go wrong kind regards colin from croydon surrey England 👍 👏 love his videos

[cjsebes]

Thanks for the video. Following your steps, I was able to get my Troy-Bilt 3550 watt genny with a Briggs & Stratton engine running again, although my coil was still good. The thickness of the business card was apparently too much. On a hunch, I tried setting the gap with the fine sandpaper that I used to clean the rust off the magnet and coil. Reassembled and it fired right up. Thanks again!

[joesinakandid]

Just something that is often overlooked - an internally broken plug. Not using a spark tester and just pulling the spark plug, plugging the plug into the plug wire and grounding the plug WILL work - unless the plug has broken inside. The big truth is that spark plugs don't last forever. Really good video, Dony - keep up the great work. 😏

[shanerogers]

This is EXACTLY what I needed to see. Thank you soooo much!!!

[Anton_]

10 year old video and yet still solved my issue thanks brother 👊

[annai]

Great video. I loved the business card gap method and by watching the video, I realized that I had the coil on backwards. Flipped it around, gapped it with my business card and it fired right up.

[muhammadakram]

this is the most easy way to teach in practical, welldone . your method in simple helped me lot to learn repairing of generator at home .

[leoramirez]

that job was awesome I tend to sand off the flywheel and the coil first before replacing it because sometimes the rust stop's the current great job

[tommielee]

Very nice to have someone like you. My Chinese knock-off always started first pull no matter what. But suddenly quit for some reason. The coil showed no signs of failure and the fix-it shop confirmed that it was good. After some head scratching and a new spark plug I found the problem to be a poor connection from the coil wire to the boot. Some twisting and turning gave me a renewed hope. And all is well. Much thanks.

[sierraridgereaper]

Thank you for a great video. Nice and clear instruction and communicating the steps. Was having an issue similar until I read a comment below about the " little brass thingy" (low oil shutoff). I unplugged my low oil shutoff and got spark so thank you. It had me stumped until I read that.

[spacecowboy]

I think this is my 3rd time around watching your video on ignition coils. Very interesting troubleshooting technique. I recently had an issue with a bad ignition coil. I mean one day it was working and then oops that has never happened before my Honda didn't start on the 1st pull nor the 2nd and nor the 3rd. It plain out wouldn't start. So thanks for being there for us when we wind up with an instant headache.
