Ok. I took a good hard look at everything under my hood and I feel fairly confident about the install.

Heres the one thing still bothering me.

Does the 69 Chevy 307 have timed vacuum advance or full vacuum advance.
I.E. does it always have vacuum or does it only have vacuum when its not at idle?

Apparently this is VERY important information on installing this carb.

Any help is GREATLY appreciated. And thank you for the post oabout the site. It had a LOT more info than I could have possibly expected.

Thank you dearly in advance.
