Clone engine will not shut off with the kill switch. I shorted the thin wire from the coil to ground and still stays running. Pulling the spark plug wire is he only way to shut it off. So I checked continuity from the wire's tip to ground and beeps (audible on). Checked continuity from the wire's tip to the coil's metal body and it beeps. Even took the coil off the block and checked continuity from tip to coil body and get continuity. So why will it not shut off?
