Ok I got a vacuum gauge and a compression tester. I tested the vacuum from the manifold with all the vacuum lines still attaceched correctly.

Findings;

At start up: did not idle up correctly, idle was low but stable.
900 RPM
12 to 12.5 in HG vacuum
With a fluctuation of .5 (seamed to be very stable)

After about 20 sec (without pushing on throttle) idle came up to:
1250 RPM
18.75 in HG vacuum
With fluctuation of .25 (again very stable)

After warm up (about 1 to 2 min):
1100 RPM
19 in HG vacuum
With fluctuation of .25 (very stable)

Ok so here is where it gets interesting. I manually added throttle, it reves up fine but then as it idles down it almost dies. Vacuum and RPM both drop to almost 0. Then I add a little throttle and it comes back up. I let off the idle slowly and it stables out at normally idle.

I can also here some odd sounds coming out of the engine. Really not sure how to describe it. The sound seems to line up with the firing of the cylinders, almost like a valve issue???
