That’s why I just bought the whole new carb. It’s almost impossible to get all the varnish out of one if it has set for a while.
I am with @wanna_be here. I think the coil is weak. Yes, I It’s firing but not strong enough. My buddy with the welding shop says, either a coil works or it don’t. Hmmmm… I’m not so sure. The last time I got the shit knocked out of me with an ignition wire I knew it. This just doesn’t seem to have enough zap.
It could even be the gap between the magnets on the flywheel and the coil. If you have gap gages it’s easy to check and set, but even if not, I just butt the coil up against, then budge it back like a hair. Just so that there isn’t contact with the flywheel.
Gauss fields can be pretty sensitive. I think you can even just use a piece of paper to set the gap.
That would be relegated to paperweight at that point.
I have a few little super magnets left from some automated weld systems I used to fix. After repeated over-heating exposure they would become weak and need replaced.
Even when weak those little buggers were pretty strong!
I am not buying it a new flywheel those are like $70. My “he really is a rocket scientist” buddy thinks it could be the plug wire itself, not the coil. He said the same as PimpDaddy, it either works or it don’t. I told him it’s all one piece so… Honestly I should have just bought the damn spark tester, which PimpDaddy insisted I did not need if I just put my finger in the plug wire and pull the rope
There’s a reason I have never gotten the thing running.
A lot of coil problems I see is they start breaking up when they are hot, runs good cold, runs bad hot. Plug wires build up resistance and eat up a lot of an already very low output ignition system when old
Those clear little spark testers that stand in the gap between the wire and the plug work decent for small engines, they are trash for modern ignition systems, but I like them on lawn equipment. Usually dirt cheap and you seem to be working on things a lot, might be a useful tool
Lol! He has built several RatRods so he is a decent mechanic on certain things. Maybe small engines isn’t his thang. He DID catch his zero turn mower on fire once
I enjoy your log and hope you’ll continue with it again. But I get it. Sometimes it’s best to turn off the noise. I hope you get whatever it is you’re after.
