[QUOTE="Pappy, post: 498330, member: 3278"] [B]Electrici[/B]ty [B]is lazy. It will always find the path of least resistance to ground. If you had no ground you would have no spark. The secondary coil windings find their ground by passing through the spark plug electrode, arcing or sparking and grounding on the tang where you set plug gap. Your coil primary is grounded to the mount boss. Reset your mixture and lean it to the point of a cough or sneeze then richen just a little. Engines that are too rich or too lean will take a bit longer to start. Properly tuned your engine should produce very little smoke at idle and be very smooth running with little powerhead shake.
