You mean where to place vac hose? if so on carb find ported nipple ie. no vac at idle vac as throttle opens.You mean 8 BTDC or 8ATDC if no trouble starting go for 8ATDC. Adjust vac advance to full advance at 1800roms.

no I should have been more clear, Inside my vacuum advance canister on the distributor, there is a adjustment that you can do to make the vacuum advance come on later, or as soon as the vacuum is applied to it. It is a small allenwrench that fits inside of the inlet for the vacuum line.

you want full advance no sooner than 1800rpms.
I would want adv to come on as soon as possible
