Well, nobody seems to be around to help me out with this major engine destruction (pics) and the questions I have asked in THIS THREAD So I'll ask this question here. I am having screw bolt problems, they are tight and soft as lead almost and they are stripping badly (how did they get them in without a scratch?!?!) and have a philips slot. Want to replace those with allen bolts. Anyway, I am going to my brothers place tomorrow, he has a drill press, seems to me that it would be better to drill these things out than to go out and buy 'easy outs' or whatever they are called. I am expecting to have to tap them holes out to a larger size, should I go M10? Can I take the halves off with the small gear still on? If I strip my brothers gear puller as well, how else can I get the dang thing off, propane?
