Adjustable Vacuum Advance
Connect the vacuum advance module to a ported
vacuum outlet above the throttle plates. The vacuum
advance on this unit can be adjusted by inserting a
3/32” Allen wrench into the canister inlet which houses
an adjustable Allen head screw. See Figure 1. Before making
adjustments, turn the screw clockwise until fully seated.
Turning the screw clockwise retards advance,
turning it counter clockwise increases advance.

• On
modifi ed engines with oil pressure above 70 psi (cold), the gear should be broken-in with racing grade mineral oil.
• Monitor gear wear after several hours of break-in. Check the gear for proper mesh, alignment, and wear.
