Re: setting timeing pointer

First pull the plugs out.

Then temporarily set the timing pointer half way in its adjustment slot. Install a piston stop tool in number 1 cylinder. Turn the flywheel clockwise until the piston contacts the end of the tool. Adjust the tool to 12* TDC and lock it.

Mark a line on the rim of the flywheel adjacent to the timing pointer. Now turn the flywheel CCW until the piston hits the stop tool. Mark a line on edge of flywheel opposite pointer.

Using a measuring tape, measure halfway between the two marks. Mark this "mid point." If the mid point line and the cast in TDC mark on the flywheel are the same, the timing pointer is correct. If not you will need to turn the flywheel to align the mid point mark with pointer (hold flywheel in this position.) Loosen pointer adjustment screw and move pointer to align with cast in TDC mark on flywheel. Tighten screw.

Now check the timing with a timing gun.
