[QUOTE="Robert48, post: 454615, member: 23401"] I have done every test I can think of. First, cleaned, sanded and/or filed all ground and positive connections and cleaned with contact cleaner before re-assembling. Swapped plug wires and plugs to no affect. Swapped plug wires from upper and lower coils and motor would not even start. Switched them back and motor starts again with either no or intermittent spark to lower cylinder. Pull wire from upper plug and the motor dies. Pull wire from lower plug and get varying results from nothing to motor running very rough. Disconnected kill switch wire from upper coil just to rule that out with no effect. Again, never had this problem until I installed the new power pack. Tonight I will re-install the old power pack and see if pulling the lower plug wire has a different effect. If the results are the same I am thinking the lower coil is bad. If results change I am thinking I got a bad power pack. [/QUOTE]
