So I just built my china girl and she was running fine.. but then I lost my idler screw. dang it. So I'm getting a new one. But after I had finished putting her together I still had a greasy piece left over that looked kind of important. I learned from thatsdax that the piece is called the "engine sprocket and clutch hub puller tool." I'm quite puzzled as to how I'm supposed to be using it.. Anyone got an answer?
