WARNING
Don't try to fully seat the distributor using the distributor retainers. If the distributor will not seat by hand, it's not properly aligned
with the camshaft. Rotate the crankshaft until the engine is at the number 1 cylinder TDC (camshaft sprocket pin at the 9 o'clock
position). Rotate the distributor coupling until the camshaft sprocket pin slot aligns with the distributor base timing mark. Install
the distributor using hand pressure to fully seat the distributor.
Install the distributor assembly into position with the driveshaft in the end of the camshaft. Rotate the distributor coupling
until the camshaft sprocket pin slot aligns with the camshaft sprocket pin. Slide the distributor onto the end of the camshaft
