Just a silly question. I am a little confused. You say you can't get full gear mesh but you havn't moved the engine. How are you trying to get full gear mesh if you don't move the motor? Are the gears worn on one side or something? Seems they would mesh if the engine is straight and the gears arn't worn. Oh, I'm not trying to make you look bad or anything, just wondering what is going on with your gears ok?
