I was running great then motor stop, was able to limp in it seemed that I lost a coil motor would not get on step, when I checked the motor out found the brown wire on the power pack was broken so I repaired the wire, went to test engine after the repair I had the same situation, The engine is old and I recently found a couple other wires on the terminal block that were bad so I repaired them also, Bought a new power pac and set of coils ,replace them still the same situation, I also replaced the plugs, still the same situation, I know I'm getting fire and fuel also cleaned the carb, I also have great compression, the linkage checks out . has anyone encountered this situation or can advise me in which direction to move forward, Thanks
