I have a 1973 Honda cb 350g and the engine wont turn over. I have tried soaking the engine with diesel fuel trying to loosen it up, but it hasn't worked. Is there a way to get the engine apart with out taking it off the frame. There are 8 studs that go through the engine and I wasnt sure if those could be unscrewed or not. I got the cylinder head cover off, but that all that I can squeze out of there. Is there a way to get the cylinder head off so I can get to the pistons?
