Well plug on bottom of light won't stay in..I was brain farting last night..to advance it I turn the distributor counter clockwise..and since the motor is spinning clockwise the top half of the hash marks are advance not retard.....it's really frustrating that my brain is fukt....thanks again guys for baring with my forgetting simple things..umm like oh ya it fires once for every two strokes......I'm probably more frustrated with myself than you guys get at me for asking questions I first knew and learned over 20 yrs ago
