Remove No. 1 Spark Plug. Turn the engine to bring the No. 1 piston to the top of its compression stroke. This may be determined by inserting a rag or your finger into/over the No. 1 spark plug hole and slowly turning the engine over. When the timing mark on the crankshaft pulley aligns with the 0 on the timing scale and the rag or your finger is blown out by compression, the No. 1 piston is at top dead center (TDC).

Install the distributor to the engine block so that the vacuum advance unit points in the correct direction.

Turn the rotor so that it will point to the No. 1 terminal in the cap.

Install the distributor into the engine block. It may be necessary to turn the rotor a little in either direction in order to engage the gears.

Tap the Ignition switch/starter a few times to ensure that the oil pump shaft is mated to the distributor shaft.

Bring the engine to No. 1 TDC again and check to see that the rotor is indeed pointing toward the No. 1 terminal of the cap.

Points = .016 gap
Timing = 5degrees BTDC
