I've been trying to solve a intermittent spark problem on a 2000 Rancher ES. I've had a heck of a time trying to determine what's causing it to spark when pressing starter then again when I release the starter button. I've tried 2 different CDI, voltage regulator, ignition coil and spark plug. I just got a pick up coil and was trying to pull the recoil bolt off when I came to a stand still. I bolt being in the rear is a pain to get to but with extensions, I'm able to get a wrench on it. It will not budge. I soaked with PB Blaster, tried a pull bar, impact wrench and even heated bolt head with a torch. No movement at all. Does anyone have any suggestions for breaking this bolt loose ??
