well after the truck sat during the winter it doesn't want to come alive no more. i just put in a brand new os8 plug and changed over to the roto start back plate just for ease of starting. i also sealed the motor plate where the back plate bolts to and sealed the carb. the motor is getting plenty of fuel and my glo ignitor was freshly charged. this motor was just broke in before winter and last time i ran it, i do remember it shut its self off unexpectidly and that was the last time i had it running.
