While there is an optimum position for the distributor/oil pump drive gear,
it REALLY doesn't matter as long as you get the firing order right and the
rotor pointed to the same connector on the cap that has the wire going to #1
cylinder at TDC AND when both valves are completely closed.
Don't waste your time pulling the gear! Just be sure that where the rotor points
is where the #1 wire connects and the other wires are in the right order.
BTW #1 and #4 are at TDC at the same time but when #1 is at firing TDC, with both
valves closed, #4 is at overlap TDC with both valves slightly open. I would guess
that at least half of us, maybe more, have tried to get an engine to run with it
timed to fire at overlap rather than the end of the compression stroke once or
MORE!
