Timing Adjustment
Use a timing light to re-time your engine.
1.
Remove spark plug from Number One cylinder.
2.
Remove coil wire from distributor and ground it.
3.
THIS STEP REQUIRES TWO PEOPLE OR USE OF A REMOTE STARTER SWITCH. While one person rotates the engine by slowly bumping the
starter, the other holds his finger over the Number One plug hole until compression is felt.
4.
Continue to bump starter until timing mark on the crankshaft pulley shows approximately 10 degrees Before Top Dead Center.
5.
Position rotor to approximately align with the Number One cylinder plug wire terminal in distributor cap. The distributor has a ‘1’ stamped
on the body. This stamped position corresponds to the #1 plug wire position and cannot be changed. If the #1 plug wire is not located on
the post above the stamped ‘1’, the rotor phasing will be wrong.

actual reading at the crank with the timing light.
