4onthefloor....you beat me to it! I went out tonight and tried suckin on the end of the vacuum advance, didn't turn the distributor. Then i turned the distributor and tried suckin on the end of the line to hold it, it didn't hold. So i'm thinkin its got a tear in it. Its 50 years old, I can definitely see the diaphragm bein torn! So, its off to the parts store. Oh, I have to remove the distributor to replace it, dont I? Thanks guys.

a 30,000 mile UNMOLESTED original, now my daily driver! Original 6 cylinder with a rebuilt '66-'69 Saginaw 3-speed Overdrive. Synchro low! Otherwise, everything original down to the spare tire. Interior is like new. Needs paint, but absolutely zero rust.
