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

carb seems fine, however I have some questions to the auto bystarter. The manual specifies max 10 ohms between the terminals and my voltmeter reads 14 ohms - is this enough difference to mean anything?

How can i check that the cdi get the correct pulse from the pulser coil? Supposedly measure the voltage over the pulser coil ive been told, but what should the reading be?

And how can i check that there is actually gas going out of the carb? Gas ok till carb, pumped in, but as the spark seems dry i wonder if the gas is not flowing through
