I have had so many issues with these motor now I have to disconnect the kill switch wire for boat to start , and plug back in to kill motor . Hard to start has new carb rebuild, new reed valves, new plugs, new gas tank, new power pack, new battery. New plug wires, new coil assembly, new gasket adapter to power head, Need help some odd things that have happed while motor was running and kill switch disabled from power pack I disconnected battery and motor still ran had to plug kill switch to stop motor. Also motor would not start so I took out 1 spark plug and boat motor fired right up put both spark plugs in won’t start.
