b. Installation
1. Place a new gasket on mounting flange of

When distributor is properly installed, rotor
should point directly at No. 1 spark plug.
NOTE: If engine has been cranked, remove
No. 1 spark plug. Place thumb over port.
Crank engine until compression is noticed and
continue until No. 1 piston is at top dead center.
In this position, the timing mark 0, on the engine
front cover, lines up with the scribe mark on
the harmonic balancer.
