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.
I have the largest Small Engine Repair Video Library on KZread and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!

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.
Five hundred and eighty-three thousand videos later I found this video well explained and with a good solution. Thanks.
As a gen owner I appreciate your diy fixes. Very well presented for us willing to do the work.
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. 😏
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!
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! 💪
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!.
Great videos! Very helpful for anyone just starting out with small engine repair.
You help me diagnose my problem, it was just the switch. thank you. Saved me time and money.
Thank you very much. Got a generator not starting rt now. This isn't the issue but i was able to cross this off the list.
This was a great video! Thanks for being so generous with your knowledge! I just purchased a Northern Tool Powerhouse unit that seems to have the same config of every generator on the market. I wanted to make sure I understood how generators work. It is too heavy for me to take it in for service so I need to be the service guy.
10 year old video and yet still solved my issue thanks brother 👊
Thank you for showing us all these videos, you have saved me a lot of money!
Two thumbs up. You are a brilliant teacher, I wish I had a great teacher like you, when I went to school.
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!
Thank you! You saved me so much money in shop repairs!
Very well set up video and easy to follow. Way better then most of the other how to videos I have seen. Thx
Love your videos. Thanks for doing them. You are my go to guy when I'm wanting to learn how to fix my equipment.
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.
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.
This man knows his stuff, take note and you won't go wrong kind regards colin from croydon surrey England 👍 👏 love his videos
Great vid. Straight fwd and easily understood. You, unlike some, obviously know what you're talking about. Thanks so much.
What an exceptional presentation! Very easy to follow instructions about repairing the generator and not all about the presenter !
Thanks so much for posting these videos -- I'm addicted to them! So informative! Keep up the good work!
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

Thank you for that tip! I sanded both down and re-gapped my coil, genny works well now after sitting for over a year. Though rust can't inhibit a magnetic field-- perhaps it bridges and gives a path to ground or the rust erodes the metal enough to widen the gap and make it not generate a spark.
Thank you dony boy73 for all of your video’s .You have save me from many problems with my shop tools.Great educational video,thanks again.👏👏👏👏👏👏👏👏🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🍺🍺🍺🍺🍺🍺🍺🍺🍺🍺🍻🍻🍻🍻🍻🍻
Excellent demonstration! Very helpful!
Great demonstration. I've right now fixed my generator with no spark with the help of your video. That ignition module cost me 5$
That plug connector is actually a resistor. Occasionally they go open causing a no spark scenario. Same thing with resistor spark plugs. You can measure with an ohm meter. Fantastic Video! Thanks for sharing.
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.
That is fantastic! Thanks so much, I'm going to work on my Coleman 1850 and see if I can get it going... thanks for the tips!
I like how you show every detail. Great job.
Thank u for the video it really helped me, we live way out in the boon dogs, one trip to town once a month for supplys, thank u again 👍
This video should be given 5 star. It exactly describes my problem
I'm doing this tomorrow! Thank you for this video.
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.
Thanks, I'm very gratefull!! You taught me and to everydody how to test and replace the ignition module in a simplest way,!! I have to buy a new one to the mower!!..
Watching your videos have save me a fortune Many thanks Barry ( England ) top tips
Your videos are very very good . I got my generator fixed. Thank you very much
Thank you so much! I have cleaned the carburetor, checked oil, changed gas.
Thanks for the video. Helpful to the point and not long winded.
I learned alot from you, good teacher, keep up the good work. Thank you!
Thank you very much for this video that taught me in an entertaining and simple way the essentials about the operation of the ignition coil of a portable electric generator. After searching a lot this is the most accurate video
Thoroughly enjoyable. Good information and as always well explained. You sure have a wonderful gift and I can imagine the wonderful sense of achievement that must come with every little challenge as well as helping people. Thanks a lot for sharing.
thanks so much Dony, I have a Honda HRS 21 GXV 110 1103002 lawnmower that was working fine until it decided this srping to start and then slowly to shut off, I will check now the spark and thanks to others videos I will also check the carburator. Knowledge is truly power thanks again !
great video. simple and to the point. I really appreciate it. this seems to be what's wrong with my saw
Thanks for the great video! You just helped me diagnose and fix my Honeywell HW4000.
thank you sir very use full tips. god bless u. today i face this problem and i see vedio slove me my gentretor problem. thank u sir
Really enjoying your videos. You explain things really well and show great close ups of the things you're doing. I'm fully confident doing the things you've demonstrated. Great work!
Just did my first valve adjustment on my Honda GC 135 pressure washer. Is running and starting great. Thanks donyboy.
Hi Donny Think you should have tried some emery cloth on the coil and magnets before changing the coil,be a lot less expensive for the customer.Good video

Great video, I picked up one brand new not working. Found out it had no spark. Looks like the coil. Thanks so much!
good point, I had done that but forgot to video tape it, thanks for the reminder

Thank you for the clear and understandable video! It was just what I needed to trouble shoot my generator. It's working fine now. 👍
OUTSTANDING, THANKS. I have a 10 year old Champion generator with no spark. Your info gives me the next step and hope I can find parts.

I failed to place my plug on the engine for a ground so whether that is why I didn't get a spark or it was a bad plug, I got a new one cross matched at car parts store. Grounded it, got a spark, put it together and cranked 2nd pull. Thanks.
Great work as always. I'm gonna try doing this to my generac 5000 this weekend
Great video, very helpful and precise 🙏 thank you so much 😊
Awesome tips! Now i'm ready to fix my wife's old 1999 Honda EM5000 for this 2021 huricane season🌀. Thank you.🤝 🤗👌
Very good video, is well explained, well done and training for me, I working now on a generator with coil problem! Thanks Donny!
Well put together video. Very easy to follow and understand.
That flywheel and magnet were so rusty, I wonder if cleaning it all up with sandpaper along with cleaning the ignition coil if that would have fixed it. Great video as usual Don. Thanks.
Thank you for the video, new to the channel but have been addicted trying to get caught up.... Wife has even given me a hard time about watching too many KZread videos. Thank you for showing how you determine what was wrong, I find that to be the most difficult part for a weekend worrier like myself. Thanks again Sir.
Fantastic! Glad I saw this before giving it away at a garage sale!
Very clear explanation. Thank you.
I had same problem , I checked the coil by multimeter and found OK. Then I closed the gap between the flywheel and the coil as small as possible and dinaly i got the spark, thank you for the video
Thank you for sharing all your knowledge.
Excellent video, Dony. Really good audio and lighting, and your editing to avoid wasting our time is superb.
Thanks so much for this video! Generator wouldn't start and storm was starting! Worked like a charm!

Thank you for simplifying the process. It helped
That's is a EXTRAORDINARY VIDEO teacher doniboy73!!!
Another clear and concise vid. Keep them coming.
Thank you Donyboy you are the Man ! Fixed my problem...
Thanks for the easy to follow procedure on a no start no spark condition.
Great tutorials. I'm not a mechanic, have no experience at all with this stuff, but the few videos I have seen make sense. I even changed the starter cord with your help! As far as this video is concerned, how were you able to rule out the spark plug as the cause of the problem vs. the ignition module? My Champion Category 5 generator won't start after >1 year of no use. Already drained the carburetor, added new fuel, used engine starting fluid, and replaced the starter cord (which I broke in the process of pulling on it a thousand times). Thanks again.
I have found on many occasions I have cleaned the fly wheel and the coil and I have got my spark as you know rust is a very bad conductor it has worked for me

also add little grease and it should help preventing the rust to come back of course you can also do that to your battery terminals
Great! I'll try this on my faulty generator. Thank you! :)
Easy to watch and listen and learn....Thanks.
Great Video! very helpfull, grettings from Venezuela
Excellent video saved me a headache. Thankyou 🏴
Merci pour la vidéo et votre informations ☺
Thanks Don, I'll be doing this a little later today!
An excellent video again. You are the best on making these videos, Dony.
Nice. You may have helped me solve an issue with a Honda GX390. I was thinking it was the ignition coil.
You did an excellent job!!!! Thank you!!!
donyboy73 - You are one cool guy! Many thanks for a great Ignition Module video.
Great vid as always, i need to re do my work bench, great work area you have :)
Thank you for sharing, I wish in future you can make a video to clean the carburetor. Excelent Video.
Excellent video and easy to follow, thanks for sharing.
Another nice one Donny. I have the no spark problem with my old Honda G200 which has not been used for the last three years and is a bit-very-- neglected. I've just been through the first procedures and will now go on to the final regarding the coil. I hope I can get a spare coil if necessary. The local engine supply shop here in Thailand is like Alladin's cave. I have high hopes. Thanks again for the very clear instructions.

Hi friend, I like your video and the way you explain is simple and effective
Fantastic..WELL DONE!!! THANKS!!
Great video thanks man for all the help you provided i hope you always do well
Hey man, your a god send, I've just changed the ignition coil on my generator, reassembled it but it wouldn't start, I didn't know there needed to be a certain gap between the coil and the flywheel, I nearly threw the damn thing away, but I'm now gonna try again with your advice... Thanks a million buddy and good day to you from England :-)

It didn't work Donny, mines a kipor ig2600, it's different I don't think the gap is important on theses, I've just took it apart again, and noticed, I've still got no spark, im now at a complete loss :-(

Instead of using a business card, try something thinner. I used a business card to gap the coil and wasn't getting consistent spark. Instead, I gapped with the thin piece of sandpaper that I was using to clean the magnet and coil. The more narrow gap did the trick. Give it a go.
Awesome, thanks, did learn. Editing my comment decided to share just what I've learned I learned I can unclip that wire From the Magneto Making that 1 less connection I have to make when changing the panel On my 4375 predator I have discovered a problem in my panel I was hesitant to change the panel Having to make so many electrical connections not worried about it anymore have a great day
Thanks Don , I had to raise my fuel tank to access the bolt on the left. I have a 4000E energy storm.
