Adjusting timng with Vacuum Advance

Yes, the intail is where you set the distributor and lock it down. Try plugging the vaccum source on the carb for the distributor, set intal timing @ 5*'s advanced, with a fully warmed up engine and a RPM gauge, rev it up to 2600, set the distributor @ 32 BTDC, lock it down.

Then hold the RPM's between 2000 and 4000 and find the total mechanical advance. Limit the total advance to 52*'s. Hook vacuum back up.

This is general and should get you in the ball park, very close. Tune for highest vacuum while your at it.
