Norm, not the choke, I have a CNS V1. 32:1 oil mix in the fuel. I run a Puch Hi-Compression head and I have a NGK BR9HIX Iridium plug with less than 50 miles on it.
I'm thinking DTG has it: CDI box. I got jaguar's CDI and it has performed flawlessly so far. I have a friend who's a electronics wiz, I'm going to have him take a look at it. Tomorrow I put the old stock box on and try it out. If it still chuggs then it's the magneto and I'm thinking sheared woodruf key but my moneys on the CDI![]()
