Hmm, I'm still having problems..
Have tried with a new rectifier and different CDI - still no spark when start motor runs. With the other CDI, I hardly saw a spark at all. (With old CDI I see spark once after start motor has run)
Seems to me that the electrical setup is fine, have done pretty much all the checks I can think of (but not the start engine itself). Could it be something with the carburetor, chocke or something that also messes up the spark? The spark plug dont get soaked in gas, so might be some trouble in the carburetor - guess I'll have to work from that side now..
tips on what to look for is much appreciated. I have the Kymco manual
