I'm working on some issues with carbs and timing and was wondering these things:

1. What is a good baseline for hg measurement for the distributor vacuum advance hose out of the center carb?
2. Is there any adjustment on the vacuum canister for a stock dual point distributor?

When hose is plugged into the distributor car will not idle correctly because it's advancing. If I unplug hose, engine will die. Seems to run better when hose is off and plugged.

Distributor has been gone thru and setup by Jeff at Advanced Distributors so I'm pretty confident it's in order.

I'd really like to use vacuum advance as it's intended but it's not a deal breaker and I was thinking I could just make it non operational but it makes me wonder if something else is going on that's causing the high vacuum.

Thanks for the help.............
