Spent all gd day f*cking with this thing. Ran yesterday fine. Today she starts, runs rough then I need to go about half throttle to keep it at idle then, nothing. Now all I get is an occaisional fart type of backfire. I swapped everything I have except the ignition coil. I only have the one.

BTW, what moron thought up that POS?

The cap has about 9 parts and you can't get continuity through the little rod thing. Anyway, I swapped stators, did the harness's, went over all the the usual suspects. Got fed up and swapped the lowers ala complete with the one I know works, still just a fart every once inawhile. I get some spark when I lay the plug on the head, nothing to write home about. Plug is wet. It's new and wet, no color. I put in the old one that worked and the same sh*t, nothing.

This sound like an ignition coil to anybody?

If so is there a good replacement? That design sucks ass through a straw!

If not, any other ideas?
 
OK

Stator is reading ballpark good. On the ignition coil from orange wire prong to ground (mounting lug) I get about 1.5. I get nothing on the wire and I get nothing through the cap, yet I get some spark from the plug when I lay it on the head.

Anyone?

Negative

Was the coil. I bummed one off my buddy and she fired right up. Smokes like hell and eats gas something fierce. Gotta lean out that 34mm a bunch. I got a 140 in it now and only have a 150 and 155. Time for some jets.

Now, it's time for hockey!!

More later,
