[@mikevanhook6683]

Right on Steve that's how I do it the only other thing you do suggest it's just double-check the gap between the flywheel make sure nothing's come loose or the Gap hasn't changed as long as you're good that's exactly what I

[@BjornV78]

In the early 2000's, a friend of mine raced Pocketbike competition, in the so-called Proto class. I helped him with the technique (former car mechanic) before and during the races. In the Proto class we were allowed unlimited tuning, only the cylinder capacity was not allowed to exceed 50cc. In terms of ignition, we gained a lot of experience back then, and also learned from the mistakes of other riders. We had noticed that the gap between the magneto coil and flywheel was very important. We and others always thought that this gap should be as small as possible, until one day we adjusted this gap with the thinnest paper we could find. The engine sounded more powerful (and also reacted more strongly to the throttle), but the maximum rpm was suddenly more than 2000 rpm lower (normally we had around 15000 rpm, and then suddenly only around 13000 rpm). What we then noticed was that the magneto coil and flywheel were burning hot, and that the plastic of the magneto coil started to smell. Afterwards we adjusted the gap back as before, but we still didn't get back to 15000 rpm, and at high revs the engine started to stutter. After a long search, we replaced the magneto coil, which took away the stuttering, but we still didn't get back to 15000 rpm. When we eventually also replaced the flywheel, we reached 17000 rpm. When we did tests afterwards with the old flywheel and the new one, it turned out that the magnet of the old one had lost strength due to the extreme heat. Afterwards we learned that the extreme heat development has to do with so-called "Eddy current" which magnets can develop, and that a too small magneto coil gap acts as a brake, and that after a certain time, this causes permanent damage to the magneto coil and flywheel. Afterwards we simply folded print paper double as a gauge and we have not encountered that problem again. The gap also determines the ignition timing to a small extent. With a smaller gap, the spark comes earlier.

[@monarichardson1556]

I was just wondering about whether or not leaning towards a smaller or larger gap made a difference. TY 4 sharing

[@2observant]

What good and helpful info - Like the other commenter , I too, was wondering the effects of gap size. Your comment is useful to me, thanks.

[@matopezuta2050]

Don't forget there are still a lot of older engines out there with points that should be checked before replacing the coil.

[@aldinnidla770]

Thats right, good good

[@harryshector]

And, across those points is a capacitor (Condenser), which also can fail, either shorted - which will mean no spark, or open/dramatically changed in value, which can lead to very weak spark.

[@DirectoutdoorsTV]

What is the "points"

[@SoothingSounds-kq6yg]

That's a good point.

[@randymartin5521]

I have learned more about small engines from your channel than anywhere else. I guess I have been fortunate in that in my 58 years, other than having to rebuild one carburetor on an old push mower and replacing the deteriorated fuel lines on my chainsaw, I have never had any troubles with my small engines. Other parts of the machines have worn out while the engines were still going. Proper and timely maintenance go a looong way toward ensuring trouble free performance.

[@Smalltechguy]

Yes Steve, I missed the other days prior. Working a Cud Cadet XT1 with a no spark condition. I cleaned all the rust off them both to include the grounding points. Set the air gap and still nothing. I've not pulled the ground of yet to verify. I also checked the key way just to make sure it didn't jump time and not spark when it's supposed to.

[@paulmcreynolds1774]

Great advice Steve. That will save money for your viewers. Thanks.

[@motorcoachtech7615]

Don’t forget to check the coil mounting posts for corrosion. Clean them up, reset coil gap and recheck for spark. I have had this a couple of times.

[@tomwincek8310]

Same here. After cleaning the mounting surfaces and setting the gap with a business card, I was cautious to not over tighten the mounting screws into the aluminum housing for fear of stripping out, but I was under tightened. When the flywheel passed under the magnets, the gap closed and I had no spark.

[@RaysLaughsAndLyrics]

Good advice...Or use your Multimeter to check resistance and continuity.

[@cedrichollowell856]

Agreed. Steve presented a method that is quick and simple and works. I don't necessarily just look for a just replace this part so I'm with you on the multimeter. Something to add is that the coil and wire and spark plug boot CAN be replaced as individual parts. The multimeter will help you get down to the specific fault. Many people look at how many settings are on the meter and hear words regarding electrical theory and get intimidated. Truth is using the right tools will save you money.

[@RaysLaughsAndLyrics]

@@cedrichollowell856 True comment.. Keep your options open. Thanks for sharing.

[@paulmaxwell8851]

With the old-school ignition coils, the ones tied to points and condenser (I'm working on one right now, on my old Stihl 028AV chainsaw) the primary and secondary coils within the coil CAN be checked with a multimeter. Today's solid state ignition modules cannot be so easily checked because of the electronic components inside. Just follow Steve's advice: disconnect the grounding conductor and spin the engine. You'll either see a nice hot spark or you won't.

[@czellner00]

Hello Steve, I just watched this episode. so, the issue I'm having is with Americas Sweetheart John Deere... he has a Japanese Heart. that won't start. (No Spark) Back Story: my sone gave me a JD RX-73 riding mower. It ran briefly and they would not start. so, he and a "Mower Mechanic" worked on it and it won't start. I am not a dummy to small engines. and I taught my son well. He ended up giving me the mower after replacing the coil & Plug. thinking surely, he over looked something I tore into it. This is a Kawasaki 9 hp motor (Model FC290V). Two things strike me as odd about it. first it has an Igniter....I've not seen that or had issue with on ever. so, I replaced it. My Son replaced the coil, so I Olhmed it out seemed ok but I replaced it anyway because I have noticed an up tik in new parts being bad from the git-go.(Oh BTW, amazon takes back coils) still no spark. the Flywheel is rusty... LOL because it's cast iron. and that happens I know. HOWEVER, the flywheel has a replaceable magnet. (Huh wth why is that?) I did the screwdriver test on the magnet and compared to other mowers, Pressure washer motors and seems fine. still no spark. What I did find odd was on this coil, there was no real adjustment for gap. so, I measured it at .015. still won't spark In closing two coils, a new igniter, two spark plugs, and with the ground terminal disconnected still no spark. it defies mechanical common sense. replacing the motor is too expensive, when I can pick up another used riding mower for $500 running or not. What say You?

I tried disconnecting the ground wire as you outlined in your video... still no spark. I traced the yellow wire back looking for a short, and it all looks good. I am at a loss...

[@jasong7374]

Another thing to try in regards to ignition module diagnosis is corrosion where it is mounted to the block and not getting a correct grounding to the laminations,it is rare but does happen,had a few in the early 2000s on the Stihl MS 660, Thanks again April and Steve, well done

[@josephrich6014]

Also possible that bad connection in sparkplug boot. Should test resistance with multimeter.

[@jasonbusch3624]

I always check the gap on the ignition module. I had a small 2 cycle engine that had spark and would start and run but it was very hard to get started and would die and acted like it ran out of fuel. I re gapped the module closer and it starts on the first pull and runs like new.

Steve, rust on that coil where the 2 points pass the flywheel sometimes get rusty enough that the intensity of the spark is reduced. I have seen this several times. Take off the ignition module and sand those 2 points and for me it has worked..... sometimes

[@popsfoodboat4941]

Totally agree

[@edwardde3]

Great Videos, keep them coming. I learn a lot every time I watch one of these! This time I was struggling with a older 14hp Kawasaki motor FC420V/AS10 on a John Deere LK172 that did not have a spark. When I first tried testing it with this method I pulled the wire directly off the coil and still didn't get a spark and thought the coil was bad because this ignition circuit has an Ignitor Module in it which still has to stay connected (I disconnected when pulling the wire off the coil). I saw another video specific to my motor that showed disconnecting the kill wire before the ignitor so the ignitor module was still connected to the coil. The actual problem was the ignitor module, which was screwed to a shroud rather than directly to the motor. Problem was resolved when I jumpered case ground to the ignition module mounting screw.

I'm working on an older Husqvarna weed eater in which nearly all the insulation covering the wires that go to the start/stop switch has fell off. No spark. I'm hoping that replacing these wires will cure the problem. You have to remove a bunch of screws & separate the motor from the shaft to even see the coil.

[@AP9575-jd]

Ya gotta make sure the iron bars have a good ground to the block, i.e., the mounting screws. If it's corroded under the coil and not making good contact with the block you will also get a no spark or very week spark issue.

[@dennisperkins1989]

i was having trouble starting my stihl MS181 and decided to check the plug and coil, no spark at plug but coil tested ok. When i pulled the plug lead out of the retaining clip i found that the green kill wire and the black one were both stripped as if the plastic cover had been stripped back wit a knife rather than worn looked rather odd as i had owned my saw since about 2016 i had not lent it to anyone nor had it been back in for repair , anyway i separated the wires and taped up the bare ones and replaced them in the clip except for the plug lead which i put beside the clip. i replaced everything and it started the first time. and since it has started better than since new. i dont know how the wires became bare but i imagine what was happening was that with the wires being bare they interfering with each other and the plug lead.
