KO= key on as far as the voltage readings the 12.25 was at the unplugged CDI with the key on and the 10.4 was at the same plug while cranking.  That being as it may I now have spark, I believe it was a bad connection on the coil.  However (I'm going to show my age here) back in the day when there were distributers and 1 coil on a car there was a ballast resistor mounted on the firewall to drop the voltage to the primary windings of the coil to 9 volts.  Well when that resistor went to the bad the engine would only run with the key in the start position and die as soon as you let the key return to the on position.  That is basicly what is happening to this scooter.

Thoughts?

Thanks,
Bear

Karl,
I suspect the CDI because the first time I lost spark and replaced it I regained spark but only for a short time.

Scooterfan,
I get 12.25 volts with the KO and 10.4 while cranking.

I have a People 150 that came to me as a no start. Replaced the solenoid, now states and stalls, starts and stalls. Removed and cleaned carb., reinstall, Starts and stalls, starts and stalls.   Now cranks but no start.  No spark, replaced CDI, starts and stalls, starts and stalls.  Now no spark again, what is eating the CDI?  Driving me nuts.  Thanks for any input.
