Also, be careful when removing that electronic ignition. Make sure the wire clips both front and back are carefully removed and mapped. check to see that the front clip (back side) is not accidentally grounded! This is the "engine cut off", and is actuated when the engine is "lifted". Also when removing the electronic ignition, remove the holding nuts at the ends, then carefully pull off - there is a plastic button on the back that inserts into the engine casing, and is easily broken off.
Let me know if you think you need another electronic ignition.
