40 hp mariner 4cyl 2 stroke told about 10 years old ?
Warm or cold all controls ready to start, no fire, move fast idle lever enough to move ign. plate, fires and starts right away?
Removed ignition everything looks good no bare wires no rub marks anywhere. There is a small crack on one of the pickup areas. looking for ohm readings or any thoughts/suggestions.
THANK YOU Jason"
