A couple of words of advise. After the chain is on correctly, turn the engine over with the bolt on the front of the crankshaft.(27mm).
PS If you have had the tensioner out, you MuST take out the piston and install it back in the front. It is a click type and will ruin the bow rail and the chain in a hurry. Be sure to do this before reinstalling the spring. It will self adjust (When doing this you will put it back in untill you hear one click.)
