Re: engine starts won't stop
Sure we have suggestions. The two "M" (magneto) terminals on the ignition switch short the ignition to ground to kill the engine. That obviously is not happening. With the switch ON, use an ohm meter and measure resistance to ground on one "M" terminal and then the other. One of the terminals should read "0" ohms (completed circuit). The other should read something other than 0. If one reads open circuit (infinity), that terminal needs to be connected to ground.
