ya the plactics on the timing side are a bitch to get to aswell, you shouldnt be able to slide the timing belt onto the cam gear without loosening the tensioner. your going to have to get to that tensioner or the belt will fly off and your pistons will slam the crap out of valves.

Theres only one way to put in the dial on the dizzy back on. (the ecu sends signal of when to fire spark) if that was the misunderstanding. So it doesnt matter if it spins, just turn it till it fits into the end of the cam.
