this is one of the best 6 year old videos i’ve seen in years.thanks👍🏿

When you put the sparkplug clip on the end of the sparkplug wire, you want to first stick the wire through the boot and pull it out the other side, then you want to put the clip on so that you don't have to force the clip through the small end of the boot. Once you get the clip on, then you pull the wire back through the boot till it seats in place. Great Video and thanks for taking the time to show folks how to diagnose and replace a coil.

Well done! I really liked that you gave the customer/friend a bag with the old parts. I agree, that shows integrity.

This was very helpful, especially about the magneto and coil. Mr. Robinson talked through it so it was easy to follow. One of the best video I ever watched.

This guy is great and he speaks correct English- I really appreciate this - thank you.

Thanks alot!!! Kevin followed your instructions took my weed wacker apart cleaned it up and it started like new!!!!

Kevin, I have to say that was one of the best video I've ever seen you really explained every little details! Now thats how to make a video! I'm like you I tried everything and now I'm waiting for my coil to arrive in February, I'll let you know. THANKS THANKS THANKS !!!

I had bought an inline spark tester to make it easier for my old eyes to see. I'm tearing down a craftsman that the plug is soaked and the coil is not firing with the shutoff wire disconnected. This is the new piece of junk 4 stroke with the speed start. Thanks for the video.

I love your way of teaching and also love how honest u are thank u and God Bless

As a small engine mechanic i always find people dont question their invoice when they have a fully working clean machine. If you have to take covers or cowlins off machines its always worth cleaning them and blowing them off with compressed air then using duck oil or wd40 to make the machine look like its been worked on. I have never had any complaints about how my customers machines go back to them, in fact all of them say how their machine looks like new. then they pay their bill with a smile and word gets around.

Thanks alot for the video. Very informative and helpful, particularly if you have no prior knowledge of small engine repair. I like that you are able to show all the steps clearly on camera so that we can see everything, thanks again!

I've rarely spent 30 minutes watching a KZfaq video, you my friend had my full attention. I like my echo srm-225 and this may be my problem and my solution. Thanks

Hi Kevin- I have been working on my small gas engines for almost sixty years. You learn a lot by just working on them like you do. I always clean coils with brake cleaner first to blast away the oil-dirt pathway between the poles of the coil fields and then I follow up with a fine wire brush wheel on my drill. I do the same with the flywheel magnets. Dirt and oil paths can weaken the magnet pulse induction thus failing to produce the required electrical charge necessary to produce a good strong spark. The same is true for batteries. Pick up a very inexpensive plastic feeler gauge to place between the coil and the magnets when reinstalling the coil. This allows the magnets to hold the coil in place and makes inserting the screws more easily. Just a small turn of the flywheel will permit the removal of the gauge and a perfect spacing. Keep things clean and yourself so things last longer. :-)

One of the best KZfaq videos even I could understand well done.

Awesome! I watched your video. Tested my Echo SRM 265T trimmer based on your video and $72.00 bucks problem solved. replaced ignition coil and spark plug boot. Now it starts and runs! Thank you for the video.

I'm at 22 mins and I can relate to the excitement of just adding the new parts and hoping like crazy the thing will fire!

I am very impressed with your honesty I wish all mechanics and small engine repair person would return the old parts to the customer, or at least show them what they changed with an explanation. Good work.

Best "how to fix something" video I have ever seen. Thank you

This is EXACTLY what my PE 225 edger is doing. I've changed the spark plug, fuel filter, air filter, fuel lines, and a new carburetor. Still nothing. I've noticed the spark plug looks brand new so I figured it's not getting any spark whatsoever. I'm 99% sure this coil is what I need. Thank you very much!

Thanks for making this great video, I already spent $200 for replacing coil and labor . Had I watch your video, I saved myself a couple hundred $$.

Excellent video Kevin . This is my kind of video . You're very thorough and honest . I wouldn't care to contribute to a person like you , if you will make lots of videos on the subject of small engine starts and repairs . Your voice is clear with no distractions like music . Your English is excellent , easy understood . I don't understand why you had even one thumbs down . Keep up the good work !!!!!!!!!!!!!!!!!----------------Ernest E. Johnson

This was the best diagnostic video I have seen as far as the ignition coil goes. It certainly addressed the problem I was diagnosing. I also tested the coil for resistance. Maybe not necessary considering a new coil would be $10. Just replace it. Thankyou for the excellent sequential trouble shooting video. It is excellent! Thankyou once again.

Ohhh that was the problem. It happened on my stihl fs 240 weed eater. After a week... It is now FIXED ALL BECAUSE OF YOU!!!!!. Replaced the spark plug. Air filter. Fuel filter. New carburetor. New fuel lines. Even took out the old fuel and with new fuel. Still didn't start. And i was frustrated why would this thing not work after all of this parts has been replaced. After fixing the REAL PROBLEM... it did start up. Thank you so much you are a very great mechanic! Have a good one!

Fellow Pittsburgher here. I was listening to you talk and I thought I spotted the accent. “Let me see if I can get yinz in the position” solidified it for me. Subscribed! Thanks brother, great video. Really helped me out down here in sunny Florida!

Thanks I’ll look at all your video your a great teacher I learn so much from your video thanks again

Thanks, very helpful explanation and accurate. You are a good teacher!

You are a good man, showing how to fix this for free, so that lots here could make money fixing simple issues..without discarding the problematic one and buying a new one or giving it for repair which costs almost buying a new one. Thanks.

I too found this video very informative and. . enjoyable. Making a video that branches both of these is far from easy. In order to keep the viewer's attention requires the ability to demonstrate knowledge along with a pleasant, down to earth attitude that keeps the viewer watching. Intrigued. I've worked on small engines for years and yet, I still find videos like these helpful and informative. Simple but effective. These lanyards aren't meant to pull your arm from your shoulder. If you're doing this on any two or four cycle engine, chances are the coil is the culprit. Well done, Kevin. I'll be watching more of your work.

… One thing you may, or may not have noticed in this video, He should have checked to make sure the wire end made good connection, within the spark-plug wire, before buying a new coil. It doesn't take much to take the end off, cut it back by about a quarter of an inch (most wires allow that much removal), and re insert the spring wire pin, back into the spark-plug wire in a new fresh position. Most new spark plug wires have carbon fibers, instead of wire (like in the old days), and the pin that sticks into that fiber, may, or may not, be making a good connection, which could lead to no spark, or a far weaker spark than the plug should have, causing the engine not to fire, when enough good compression, and fuel is supplied. So, before you go out and pay $50 for a new coil, check the spark-plug wire, that fits and connects to the spark plug. Over time of removing, and reconnecting the plug wire, it's solid like connect, may not be so well connected, as you think it is. The pin can pull out of the spark plug wire completely, or partly, making the connection very poor or not at all. By doing this, you may save yourself a $50 pocket expense, and wait time for the new coil to arrive in the mail, or a miserable trip to the repair shop, for a new coil (which all come with a new spark plug, cup end already installed on it. Instead of the coil being at fault, it was the connection between the wire, and the spark plug end at fault. Hope this little extra tip saves you some time , and money, and gets your engine back up and running sooner. … another small tip; take time to make sure your exhaust port is open, and free of carbon build-up. It also can stop your engine from firing up, if you have spark.

Thank you very much. This was very informative, interesting and, with your presentation, very relaxing. 👍🙂

Woooow fantastic ,I have the same problem on a McCulloch italiana hedge trimmer , done the strip down but unable to find the correct coil , but this video has given me confidence that I'm on the right track. Thank you 🤗👍

Excellent video, have been messing with my trimmer trying to trouble shoot. Thanks to your video I learned how to test for spark and identified the problem. Replacing the ignition coil was a piece of cake.

From UK thank you so much, maestro *******

Thank you for the useful video which really shows how simple the ignition system is when you get down to it. There was no need to clean the pole pieces of the 'coil' (actually the stator of the magneto) and the rotating pole pieces as, although you said that they would make good contact, you then ensured, quite correctly, that there was a 10 thou gap. There was never going to be any contact anyway!

Thanks for this helpful video. I really enjoy the calmness - the way you speak and do the job.

Hi Kevin Wow! very informative video with very precise and clear instructions and no background distracting noises I would highly recommend watching your video's any day your the man👍😊👍

I scratched my head for days with a similar problem on a mower, swapping good parts from another I had nearby before discovering the flywheel had a bad magnet. They do lose they're power (magnetism) from a number of ways, shock being one of them. I found a description that stated if it doesn't suck and hold a screwdriver from about a half inch away then replace flywheel which I did and it ran perfect. Tested it on both flywheels side by side and sure enough huge difference. Haven't experienced that with my small 2-strokes but in principle it should apply.

Man, that was a great job you did. I own this weed wacker and it is great and runs like crazy. So glad you showed me how to do that repair. I want to find your carb repair video next. Thanks alot.

Excellent show my friend, your best asset is your just a regular guy like anyone of us wanting to learn. Keep up the great work!

Sounds beautiful... My Subaru (Robyn) brush cutter has this problem, and I had no idea why it was so hard to start but I've been having problems for a while with it, I bought the brush cutter in 2010 so it's been good to me so far, I'm going to get the part next week..

Very good video ! easy to understand, and I learned a few things, thank you!

I use a paper grocery shopping bag on the fly wheel as a spacer for the coil, works pretty good for me.

Here's a second comment from Biomed. A few of your viewers have said 'why don't you test the coil with an ohmmeter?'. This is not an unreasonable question. If the coil is open circuit it will certainly show clearly and the coil will need to be replaced (unless the break is obvious and accessible). However the coil may show continuity and therefore have the appearance of being OK but if there is a shorted turn somewhere inside the coil it will definitely not produce a spark and will need to be replaced. This is not easily testable with simple test gear but if everything else in the ignition system is OK, then this will have to be the circumstantial diagnosis. For the techies the reason is that a shorted turn will destroy the inductance of the coil. Keep up the good work!

Hi Kevin, Firstly, Thankyou very much. You are too good. I watched your video on the weed whacker and I am very amazed.

Nice demo! Thanks. For an untrained small engine mech, you know what your doing. Bravo, keep up the great work.

very good video thanks for sharing !!

Great common sense video, easy to follow and full of good advice Thanks.

Nice video for helping people that are not Mechanically inclined to save themselves some money. The average cost here in NCs shop cost start at for diagnostic is 65. And 65 an hour measured on the 1/4 of the hour. So 22 minutes is going to be billed at 32.50 + 65.00 which comes to 97.50 plus tax and parts. It don't take long for the average owner to pay more to fix one than to buy a new one. Your helping people and keeping them from adding to the already disposal problems we have created with the replace it generation. Keep the good work up Kevin . Ive been working on small engines for 35years and a little good advice is better than none.

Great video 👍. Only thing I would add is I would check for continuity in the spark plug wire too before buying expensive parts.

Great video: You explain things very well that even a simple non-mechanical person can understand. Thanks for posting.

Thnx for the tuitions made easy.

Good job Kev, learned something tonight , some guys like to pass on good information and some guys just like to break ball's. Keep on fixing, it's what we do.

Thank you! I’m going to try to fix mine.

Well done Kevin! You helped me a lot! Keep up the good work and "All the Best" to you and your family!

Kevin, good job, good advice. Calm explanation. Thank you

Thank you Kevin.. You've just taught me how to fix a faulty coil

Good work. Now i can fix my weedeater. Thank you.

A credit to you no bull no music just straight to the job well done Kevin

Oops, I discovered it's possible to put the coil in backwards, which will louse up the timing. No problem, I found the right way in your video. New coil, clean plug, new prime bulb. It hasn't run this good in years. Thanks!

I like the way you talk, you talk the way I do and I love it, you made a good video thank you.

Thx u for the reply And just keep video s coming

Good vid there Kevin . I usually test for spark by grabbing the spark plug and touching the motor while pulling on the starter. You may get a bit of a tickle this way but it does give an answer straight away. Cheers. Keep it up. !

Many thanks. I'm in the same place, need a coil. This was great, everything made good sense. I'll order a coil now.

Excellent demonstration.

Good video Kevin. One thing you might want to try before condemning the coil is to clean the coil around the bolt holes where it mounts to the engine and the engine as well so you have a good continuous electrical ground path. It can become corroded at this location and cause the coil to fail to spark.

Good video easy to understand very complete in details.

Good man you are sir. Integrity is our biggest treasure. Nice video. Gracias.

Very informative with step by step illustration. Thank you

excellent video. learned a lot there keep up the good work

When attaching plug push the wire through the cap crimp the connector onto the wire and pull the wire back into the cap

Great Video! Thank you for taking the time to do it! Excellent job!

Great video. My Echo 225 trimmer had a WEAK spark and wouldn't run yesterday - changed plugs, blew out the wet cylinder with compressed air... nothing. Pulled the ignition module/coil and sanded down the 2 contact points that interact with the flywheel and then the magnets on the flywheel with 220 grit paper. .016" feeler gauge between the flywheel and ignition module and buttoned her back up. Started right up.

‘I never knew that they called it a filler’s Gage. I always thought it was a feeler gauge.

you can use a biz card as a feeler gauge -works everytime

Good video! I just learned how to check the gap between coil and magnetos as well as trouble shoot for spark. Thanks!

Very good video, Honesty, a very good advise for those wishing to start a business in small engines, you have to be honest with the customers, very important point. Overall, outstanding.

put your spark plug cap on first, the attach the spark plug connector. Now you can pull the cap over the connector.

4 things needed, proper air&fuel mixture/ compression/ good spark/ proper timing.

I like way. Way you make sure your clients understand what you did and replaced parts to see what was not working. Also you complete diagnosis.

Mine did this after 3 uses. Ive done just about everything to it. Thanks for the vid

Actually no contact is made between magnets and magneto coil, The coil works on magnetic induction. two coils inside coil housing, the primary, few hundred turns, secondary a few thousand turns very fine wire. possibly a condenser reaches a given voltage then discharges into the primary coil.

Good job i new it would run...

Great vid,just what I was looking for 👍

Well I'm impressed.loved the honest bit at the end. I'll do it.

Suggestion: Not sure cause I've never done it but the two pieces you put in the spark plugs end of the wire MAY (again I can't be certain) be easier to slip the cable through the rubber boot, connect the metal loop and pull/push it in place. Thanks, Enjoyed the video buddy.

Tip when re- installing the mag use a business card for a gapper if you aint got no feeler gage.

My 225 Lite Husqvarna was a beast. When it quit, I checked spark, good, I checked compression, also good. I checked fuel, also good. Only thing left was the mixture of air and fuel, which will be known when I get done rebuilding the carb. I believe it's pulling air like a car with a vacuum leak. Good video for the DYI.

Thank you Kevin

Thank You Kevin, Fantastic video! This really did help me a LOT as far as repairing the two trimmers that I’m working on. I made the mistake of not grounding the spark plug when I was checking for spark. Just wondering… Do you see the coil go bad pretty often?

Good Video. Suggestion . . . put the spark plug boot on 'before' the metal clip and you won't have to squeeze it through the narrow end.

Great video mate,,, look forward to some more.... Thankyou

One of the best detailed video. Well done my man.

make sure you "filler" up wth fuel

“Look inside fuel tank and make sure it has fuel in it.” This man has seen Slingblade.

fantastic video showing the basic troubleshooting pregression!

i like your honesty ..its the way i would do it kudos to you my friend

..you might have first put the plug wire thru the rubber cover, put the wire piece on and then pull it back into the rubber boot...

Heck if you went that far you probably should have clean the exhaust port and Screen to. That was a good video!!!

I enjoyed this video, I have been looking for such troubleshooting where no spark is produced.

Excellent video my friend, thank you!!
