Thanks for all the great feedback. Pretty sure the motor is dead. When I turn the flywheel by hand everything is fine. And the engine was working perfectly for weeks before there was trouble. It WAS jerking going forward and smooth in reverse but then the non-tach motor just quit. No matter how I apply power to the engine it won't turn. So I'm going to treat it as if it's dead, unsolder the wires and connect these to another motor to continue to troubleshoot. If the replacement motor spins, then I'll drop it in.
After I disconnect the wires from the current motor, is there a measurement I can make (voltage) across the wire leads that tells me that the motor is getting the correct power? It should be if the other motor is working.
Thanks
