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 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, 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 UA-cam and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!

Watch my video on how to quickly start a generator that's been sitting a long time here;

There was a hurricane this Sunday in Houston and left us with no power for three days my mom’s boos gave her a generator so we could use but it was shutting off every ten minutes thanks to you I was able to fix it and I could get some sleep 🙏🏽🙏🏽
A simple repair based on your years of experience. Great job.
Another outstanding video Mr. Dony. You’re videos are easily the gold standard…. Cheers from Ottawa
cheers from Muskoka!
I have a 4.0 hp Champion on a trash pump. Very reliable machine. It quit running the other day and wouldn’t restart. I thought maybe it sucked some grit into the carb as it was low on fuel. I did a carb clean and still no go. Checked fuel filter, another carb clean and cleaned fuel tank. Still no go. Then it occurred to me this engine has a LOW OIL sensor. Checked oil and it was low. Added oil and engine fired right back up! Live and learn I guess!
Thanks for your great channel!
DB73 You're a wizard of small engine repair. Stay safe ol Buddy.
thanks buddy, have a good weekend!
I had an issue with my 8k Champion the other day, it would start and run fine with a light load, but after about 20 minutes or sooner with a heavy load it would bog down and die. Let it sit a few minutes and it would restart and do it again. I am running on propane, dual 40lb tanks, so I knew fuel wasn't an issue. Pulled the plug and it looked perfect, nice and tan, no signs of lean or rich burn. Decided to check the valve lash since I hadn't checked it in about 40hrs of run time, and I found the exhaust valve had basically zero lash and the intake had .001-.002". Set them to .008" on exhaust and .006" on intake, fired it up and it ran for 12hrs straight without a bobble. Looks like the exhaust valve lash was so tight that when it ran under load or for an extended time, it would expand until it wouldn't seat anymore and the engine would die from compression loss out the exhaust port. Pay close attention to your valve lash on these little engines, it's important.
Thanks for that info, besides this issue, what is your opinion about this generator? I am thinking of buying one.
I purchased a new Champion 7500W Duel-Fuel Generator (model # 201040) in October 2021. The gen was exhibiting the same issue as shown in your video with one minor exception. It ran flawlessly at idle. However, when I applied a load, the gen would die out after about 15 seconds. It didn’t matter if it was running on gas or LP gas. The result was the same. I contacted technical support and the tech said it sounded like a bad Overvoltage Controller and he’d ship out a replacement ASAP. After receiving the replacement, I installed it and the same thing would happen. Since it was under warranty, I took it to the service center in Newark, NY for the tech to diagnose what was causing the engine to die out when a load was applied. The issue turned out to be two bad 120V AC 20A GFCI receptacles which, for some reason was causing the engine to die out. After the receptacles were swapped out with new ones, the generator runs great now.
I enjoy watching your videos. I even watch them when the equipment you're working on is not relevant to me. I figure at some point watching your videos can be applied to help me diagnose/fix/repair power equipment in the future. Keep up the good work!
thanks for that info!
Good video. I've had a similar problem with a pressure washer. The problem has a plugged fuel cap.
Really clear demonstration of how to logically diagnose the problem. I have not yet seen a machine with that style of valve/filter, but now I will be ready when I do. Great job Dony!
Agreed absolutely! Don has excellent troubleshooting skills! Some technicians do it the other way.... replace parts until it works, then proudly proclaim "I fixed it!" 😶
One thing I do is use a funnel with a built-in screen when refueling. That has saved me a lot of grief with keeping dirt out of the tank. Great video and thanks for posting it.
great idea!
Ty for saying that. Awesome idea!!! Great video also!!!
neighbor has the same generator and the filler for the tank has a removable screen in it.
2:10 ? One, (me) has to wonder, what were those 'engineers' thinking ? WHY not have an in-line filter, like the good 'ole days ? North America is FULL of non-working machines like this......so much for whatever happened to '' user friendly '' serviceable generators/mowers/tillers /etc. Or, at the very least, HAVE THIS FILTER, IN the machines MANUAL, under 'service' listing, in table of contents ? Thank-you, DonnyBoy, for NO BACKGROUND noise (music); and an easy to 'hear' gentle voice: non-intimidating for novice users......
Good video. I've seen it a few times where the gas cap vent was plugged and the fuel could only run out for a little while. Good Luck, Rick
Always good to start at the beginning. Fuel delivery...check. Thanks for posting Dony.
This is great, man. Thank you for the detailed video. I just got my mom's generator set fixed after watching your detailed video. It would have cost me to wait for 12 hours to get an engineer look it up and fix it while we so much need power supply right now itself
Thanks Don. Love your videos. You are a great teacher.
Thanks Don, great video. I have a smaller champion i run every two weeks or so and run ethanol free gas. All tips i got from your videos. Thanks and keep up the great work.
Great video. Instruction easy to understand and follow.
Thankyou Sir.
Really good video thank you! And the quality of your camera, the screen is really clear and pleasant to see! It s not blurry.
Informative and highly useful as always. Awesome!
I had a Honda exact same set up doing exact same thing drove me crazy everything was cleaned and functioning but believe it or not it was the plug! As the plug got hot it quit firing.
A simple fix but they all help - thanks !
I had that same problem with mine. Good information. 🤙
great tip not too many people would suspect the shut off valve, and would be scratching their head over that one!
Thanks man you saved me a grand on a new one I’m in Houston dealing with this storm almost 2 million people with out power so you know it was hard to find another one
A quick trip to UA-cam University and voila, I'm back in business! Thank you!
Very informative, thanks Dony. 👍👍
Great tip. Thank you for sharing. ❤️🇨🇦
That's a great method and so logical. Thanks for the tip!
Thank you, now if my H07552 is equipped with the same fuel valve assembly I'll check that first. Thanks, I'm subscribed and rang the bell.
Good Troubleshooting And Fix
Very nice information ..Thanks Donny
thanks buddy I have a generator smaller model I will do that for sure thanks very much take care have a great weekend
Thanks for the tip. Thats a pretty easy fix!
Life saver, this video saved me a lot of money. God bless you. Thanks.
Thanks Dony, always nice watching your videos. God Bless you and family. Hang in there friend!
thanks buddy!
Once again another great repair tip
Thanks for sharing Don. I hardly work on or see these, as I don't own on. But great info to know, just in case. Have a great weekend.
Thanks Dony, this was my problem.
Great video very clear will save people hours of messing about!
Nice tip Don Thanks
awesome thankyou so much..
Nice job 👍
❤ just love what I saw on your video sir as I'm doing having a run and shut down for almost a year now. 😢 I've cleaned a tank as many times as I can remember and finally replaced a carb. It backfires and shutdown even today. Many thanks I'm going to try this one
I love those bowl drain screws for that very reason, easy troubleshooting. I bet many carbs get pulled and replaced when it was the screen in the tank. Great video!
Thank you very much sir........I had similar issue, so I decided to come on UA-cam for suggestion, I had already bought a new carburetor when I watch the video and now my generator is back up running.......:keep it up sir, now I have the experience 😏
Thanks bro I was about to tear my carb apart going to check this good looking out
Good job
Like always
Thank you
Great information and video
Thank You ☺️
Good video to the point and well explained
Thank you for the heads up
Thank you Don for sharing with us! All the best from România!!!👍🤗👏👏👏🇷🇴
My pleasure!
Great video... your solution solved my issue. Huge thanks!
thanks as always👍
Hey, donyboy73,
watched and applied your skills to my generator and woohoo I got it!! = need new oil sensor tho.
Thanx Much - Don B.👌 L.A.
👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽 Nice video sir. The idea of adding an external and disposable filter is brilliant. We have 7 generators at my job and I'm sure this is what is wrong with several of them!!!! Thanks! 🤝🏽🙏🏽
I’m always surprised how very simple so many repairs are, and how the vast majority of the time it just comes down to following of gas is getting to engine.
Fuel valve was issue cleaned it runs like a charm thanks for advice
thanks alot, saved my life...10 minutes back up and running
I have the same generator, I was about to throw a match on it but i watched your video and that fixed my problem, thank you very much!
Hi there. Love your videos. How about removing the screen and installing a inline fuel filter?
Have a nice weekend
yes you could do that
Thank s
I have had' hunting' issues with my generator most vids have pointed to it being blocked jets. I tried clearing them and it did not work for me, so I will be checking my fuel tap assembly tomorrow. Great vid, thanks
Thanks for the video man! I'm gonna try this real quick and hopefully that's what going on
If your champion generator is shutting off without any spitting/sputtering, unplug your oil sensor. These things go bad like crazy. That's after making sure you have oil.
Love your videos!!!
Thanks, learned something worthwhile today Thanks to you. I would have blamed it on the coil at first guess. But a good plan would be like some one on here said
All the petro should be run through a screened funnel that eliminates water as well as dirt.
Thank you brother this help me alot
Thanks a lot !! God bless you
Man ion really know where to start from man!!!! Your a life saver 🙌🏽That shii really worked!!!🤍🙏🏽BIG UP FAM!
Another very useful video
Another great video.
Good useable video
Thanks
I have a Duromax that did the same thing. The gas/propane selector switch is what was bad. I just bypassed that and placed the fuel line directly to the carb. Runs like a champ now.
thank you for this video
Jeez, that machine is so clean. Is it new?
Interesting, I checked my gas shut off valve and saw gas flow right so it wasn’t blocking. Opened up the air filter box and removed the filter. Somehow it started and stayed running for 5-8 minutes before gas ran out. I added another few oz of gas and restarted. All good now. Thanks for the video and sharing what can cause the thing not running long.
Wow, that seems like a pretty poor design. But as you showed, it's very easy to fix and take care of. One just needs to know and now you just taught many people.
Great info as usual Donny
Thanks 👍
Jeez Dony... at today's gas prices you prolly bled out about a hundred buck of fuel in these tests!! LOL.
Good info, thanks.
Great point!
Interesting, thank you for posting! I find it interesting that my lawnmower (10years), never had any carburetor/fuel/filter issues, wonder why that is?
Work perfectly thanks
Thanks did the check, there was a bend in the fuel line of my new generator that caused this. Quick fix.
Thank you!
Why steel tanks are still being used is beyond me. I just got a free Craftsman tiller with the same issues plus rust. It now has a Tecumseh Snow King tank on it with the shut off and inline filter from the snow blower someone neglected and "blew up."
Well done.
Thank 🫵
Thank you.
Pull out the little screen filter from the valve, and install a clear filter inline.
Take value screen out and add a in line filter is easier to service later
This is a great simple video. Premium fuel with sea foam added seems to help a lot too.
...another great DIY video Don.....thanks for posting.....if I wanted to install an inline fuel filter between the tank
and the carb, what kind of filter would you recommend for the gravity feed system?
the filter with a screen inside
Bro you rock! Helpful asf!
Though the fuel filter was filthy, after cleaning it and the carburetor, and changing the oil, and cleaning the spark arrestor, and putting fresh gas, cleaning the air filter, unplugging the sensors, and trying the gas cap loosely on, it is still shuttng off after 5 seconds of running. But, it does sound and run smoother for that 5 seconds.... Any other thoughts? Or perhaps it's time for the pros?
Very helpful Dony thanks !
That was the problem. Thank you.
Brotha Thank you so much 🎉
Wow. Love it
I’m having the same problem, I changed the in line gas filter, which doesn’t fill up, thanks for the tip about tilting the unit back, I was wondering how I was going to take the shut off valve off , without emptying the tank
Good teacher
wish i could piss that good 😁
