The first notch on the damper pulley should be aligned with the pointer when No1 piston is at TDC
on the compression stroke. You should be able to check your mag for fire by removing the coil wire from the cap and holding it within a 1/4" of
the magneto frame and snapping that impulse coupling. Some that post on here have used variable speed drills to spin the mag when checking for fire. I'm sure whom ever rebuilt the mag checked it for fire.

When you're bringing No1 piston up on compression,
once you feel compression against your thumb stop cranking the engine and drop a screwdriver into plug hole with a thick handle so you don't lose it. Slowly hand crank the engine until the screwdriver quits rising, your first notch should be aligned with the pointer. Then install your mag. Hal

PS: When ever you remove your mag for some reason
you need to look to see where the rotor is pointing in the cap and make a note on paper. Do not turn the engine over once you remove the mag,
this is the same for tractors with distributors.
Very easy to get your engine running and back in time.
