Ok so I'm by now used to getting into the technical issues and repairing required by the 66cc engines but this one has me stumped. The other week I had to replace the magneto which I got the new one from a local shop. they did grind the gum off the mag. And it sparked for me for alittle while. But I think I over ran the engine the other day and it just failed to spark. At first I thought it was a spark plug which when I checked the plug it looked fouled so I went to a local auto shop and got an NGK B7HS cause its hot out....bought four. so I get back to where my bike is and put the plug in....no spark So I looked at the CDI which it looked old. I took a multimeter to it and one connection read 47 ohms (( I had it set to 2000 ohms. )) the other one said zero so I thought it was the CDI....replaced that....no spark. I got the CDI From the same guy I got the mag from and the CDI connections looked tanned out like they have been used....he says there from sitting...idk. At this point I'm ready to give up on this engine and get a new one. I don't want to take it to the mechanic cause he can be a pain in the ass to deal with. Please help obi wan your our (( me and my bike)) only hope!
