Default Re: Trouble shooting the bicycle engine that won't start

I checked the park plug wire and no spark. I don't think the clutch is slipping because i can feel the cylinder moving and the resistance, however i still find it strange that the motor whirrs when the plug is out and does the opposite when its put back in. Personallly i think its most likely an electrical problem, Is there anyway to individually test the CDI unit and the magneto?
