ADVANCE BUSHINGS
There are 3 different advance bushings included in

advance is desired, follow the procedures to change
the bushings.

• Take off the locknut and washer at the bottom of the
advance assembly at the bottom of the bushing pin.
• The bushing will slide off.
• Select the new bushing and install.
• Install the washer and locknut.
HOW TO SET UP THE MECHANICAL
ADVANCE LOCK OUT
1. Remove the springs, weights and the advance stop
bushing from the advance assembly.
2. Remove the roll-pin and gear at the bottom of the
distributor.
3. Lift the shaft at least two inches out of the housing,
but do not remove the shaft.
4. Turn the shaft 180º so the bushing pin slides into the
small hole on the advance plate.
5. Put the locknut and washer back onto the advance
bushing pin, which locks the advance in place.
