Thanks! that will help me out alot. I have one more question i took the fly wheel off is thier any special way that goes back on? i noticed its not keyed like most fly wheels i have removed but does have the numbers on it for the timing.

thanks for the help! And sorry about the spelling

it should have some marks to line it up, or the holes will only line up one way..but I am not real sure as I have not had any experience with that model. you really need to get a manual
