I have a Bolens model number 13AM762F065, it was torn apart when I got it. The deck was off as well as missing a bunch of parts. The motor could not be turned over by hand. I ordered a bunch of parts and rebuilt the deck and drive system and mounted the deck. I tore into the motor to find the connecting rod broken, ordered it and most everything inside the engine and rebuilt it then remounted the motor. Now I cannot get the engine to turn over using the ignition switch, it will turn over if I run a hot wire from the battery to the started. I have not been able to get the spark plug to fire at all even though I cleaned the magneto and flywheel. I am thinking it must be a safety switch and hope that somebody can give me an idea of where the four switches are? If you have any other suggestions on what to check jump on in here and let me know.
