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 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, string trimmers, grass trimmers, line trimmers, hedge trimmers, strimmers, weed wackers, 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 go-to guy.
My favorite brands of spark plugs are NGK and Champion.
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.

My Chinese chainsaw which is new has the same symptom. Run strong when cold then dies and won't start when warm. I replaced the carburetor. Same thing starts right up when cold. Why would coil fail when warm?

Thanks for taking the time to upload. Managed to fix 'no spark' issue. It turned out not to be the ignition unit but a combination of bad earth and loose switch cable. You gave me the confidence to properly open up and investigate. Cheers from SCOTLAND!

@bedwards495 3 года назад

Thank you so much for all your instructions! You've walked me thru three repairs so far and your step by step diagnosis and repair instructions are so easy to follow. So glad i didn't chuck my ms170 to the trash bin. I've probably cut about four or five cords of almond and fig wood since installing my ignition coil with your help. Again thank you.

@GregArnett-lo2ip 3 месяца назад

I especially liked the tip about disconnecting the positive wire isolates it to the coil exclusively. That made me much more confident to order a new coil. Thanks!

@martinjalbert7630 3 года назад

You made my day after my Ms660 stopped working when hot. I thought I had flooded it, but no spark, I had a coil on hand, with your instructions it was back at work within 15 minutes. It started 1st pull the next morning. Thanks.

@McKlusky2012 6 лет назад

thank you for showing us how easy it could be to find the reason with ignition problems! Great job !

@PTSix-eg4zj Год назад

I normally don't get into comments but I must thank you. I have a Stihl 012AV that most certainly had an issue with dying when it got hot. Your comment that the spark plug can contribute to this saved me! You cannot purchase an ignition module anymore for my saw...so I thought I would at least try the spark plug after your comment...it worked!!! Before the saw would fire up no problem, run great...then die once it was hot. I replaced with a brand new NGK, it fired up, it got hot, it got hotter, it screamed, it wailed...it did not die! Before getting a new module one must try a new plug first. Thank you for your help!

@paintrock 2 года назад

Thanks for all of these videos. Neither my MS180C nor my 026 Pro would start after sitting for a year. Using your diagnostic tips and some relatively inexpensive parts, I have them both up and running.

I liked the way you diagnosed the problem and fixed that chainsaw. I have a Stihl chainsaw which is hard to pull over and don't want to start for me. The saw have been in the shop several times and I still have problems with it. After the problems I have had my solution is to never buy another Stihl saw again.

@mikesmith1473 Год назад

Great video Dony, However, I would like to add one more tid-bit of advice. I have a Poulen 2250 that was driving me crazy. I had checked for spark and the spark plug was sparking fine but it would not start. Even with starter fluid it would not start. The carb was good, the gas lines were good, good compression, the spark plug was sparking but it would not run. Then I noticed an unusually large gap between the ignition coil and the flywheel. Why or how that happened I’ll never know. After I properly gapped the ignition coil the old 2250 runs like a new one. Thought I would share that with you so you can pass it on.

@speedygrasshopper9768 5 лет назад

Thanks, helped me quickly diagnose a Chinese 6200 62cc chainsaw where the on off switch was bad right new from the factory. Once I unplugged that black wire from the coil the spark plug was sparking while cranking. I'm sure that definitely means they don't do quality control or start each one up before packing them up. Anyway, ordered 5 new switches from ebay for half the price that one would cost shipped from a USA seller. While it's probably gonna take up to a month to arrive, I just turn it off with the choke, they turn off fine that way too.

@paulhaines5755 4 года назад

Awesome vid. Thanks! Think my 064's got a bad one. Runs good till hot, dies won't start. Now I'm at the point where it simply won't start and spark is present but seems kinda random or where you really got pull it to see it. I'll try the things you show here. Thanks!

@snellsentinel6485 7 лет назад

@KerryBatdorf 2 года назад

Excellent Help. Following your instructions to replace the MS 280 ignition module it now starts right up. However, at one point you mention starting problems could also be in some other part of the electrical system. Now, some time later after cutting a cord or two my saw will not TURN OFF when I move the switch to the OFF position. It sure would be nice to see more info about the other parts of the electrical system and what kinds of problems they might typically have.

@fredmartine674 3 года назад

New subscriber here, I have a 044 Stihl chainsaw. Recently, it only ran when it was cold and shut down once it warmed up but now it won't even start no more. I strongly believe it's the ignition module, haven't replace that for many years. Thanks for the info video.

Thank you for the help mate - from Australia *use a playing card 'guage' by the verniers it was 0.9 I'm getting 2 years from $14 coils from eBay - Carbs for the lower end MS series under $20 as well compared to the Stihl 'Genuine' parts.That genuine coil in OzTralia is about $80 USD

@Jocabod 4 года назад

Hi, Thanks for your great videos. I've been restoring a Craftsman 18" 42cc saw. It looks to have had very little use but the fuel lines were disintegrated when I acquired it. I replaced the lines and it started and ran rough for 30 seconds or so then it died and would not start again. I replaced the spark plug and nothing. Because it had started I didn't think it was electrical so rebuilt and cleaned the carb. Still nothing so finally checked for spark and nothing using both spark plugs. So I ordered a new coil which fits but the terminal was different as was the angle on the spark plug lead cap.which made it tight to put the cover on. Still wouldn't start and no spark even with the new coil. What should I check/do now?🤔

@michmich9826 4 года назад

Bravo merci a vous travail de pro !

@johnclarke6647 2 года назад

One of the first things I check is the position of the bayonet lug on the end of the spark plug wire. These can be undone by users pulling the spark plug wire, haphazardly. I usually take my carb adjustment screwdriver and insert it in the boot and feel for the bayonet lug in the bottom of the boot. A lot of times it has been pushed back down the end of the boot where it can no longer connect the spark plug If this happens, I pull it out of the boot , connect it back on the spark plug wire and inset it back into the boot and re-check it for spark. A lot of times this fixes the problem, sometimes not. I then troubleshoot the coil if I still do not have spark, but this is my first check. .

@chrisgould9960 3 года назад

Awesome tutorial, thank you.

@johnclarke6647 4 года назад

A business card is usually fine for setting the air gap, as long as it is .010 thick. Some are thicker. The Stihl spec is .15-.30mm, or .006-..012 inches, so a .010 thick business card is fine.

@donhatcher9796 3 месяца назад

After replacing the ignition module I tried testing for a spark by turning the flywheel rapidly using my hand. When I did not get a spark I assumed the problem hadn’t been fixed. Come to find out you can’t turn the flywheel quickly enough by hand to get a spark. Once I reinstalled the recoil starter I had a good spark.
