How does the FW stay locked in place with the wider keyway? I read about slotting the coil a bit to advance timing, any experience with that?


Well to advance the timing you turn the flywheel in a clockwise direction.   So I widen the slot on the left side so that it will still rest against that side.   You only need about a 1/16th of an inch to get around 3 to 4 degrees.   I then line up the flywheel where I want it and tap in on with a socket and hammer so that it gets tight on the taper.  Then I tighten it the rest of the way down with a 3/8ths impact gun.    I then double check my timing and make sure it is right and the taper on the fly wheel is actually enough to keep it in place.




To advance timing, the flywheel must go COUNTERCLOCKWISE!
The crank goes clockwise if you are widening the slot in it, you will remove material from the left side.
I always remove from the flywheel. They are easier to replace if you mess up!!!
The engine rotates counterclockwise and to advance, you have to get it there earlier.

Help me out here Mike.   If I am looking at the clutchside then it is turning clockwise if I am looking at the flywheel side it is turning counter clockwise is it not.
