Default Re: 70cc Old Dog Won't Start

Everytime mine pulls this garbage on my bikes it's almost always a spark issue. The CDI units keep failing for me for some reason when I leave them not running for a while. This explains why you have fuel in the cylinder and on spark plug but it's not running. The spark is weak.
