Hey - I have a 79 Puch Maxi. Compression is good, fuel flows fine, but spark seems non-existant. When I pull the clutch in and spin the petals the horn works, the light works, etc. But if I pull the plug and ground it to the frame I dont see a spark (have replaced the plug two times). I even went as far as holding the plug in my hand to see if I get shocked, and nothing....
What should I try next to get this running?
