Hello all, I have a 2002 blaster that has an ignition problem. I have a weak spark and am trying to take apart the generator to get to the charge coil. There are several Phillips head screws on the outside of the cover that I am having a hard time getting to. Is there a trick or speacial tool I can use to take the screws out without stripping the heads? Any help would be great. Thnks:-/
