vacuum leak

[joesnow]

What is the best way to find a vacuum leak. I tried starting fluid , but it didn't rev up much at all. The engine revs down slow.
Any ideas? Thanks.

Might not be a vacuum leak. Are the advance weights sticking? Vacuum advance hooked up to the ported port? How far are the throttle blades from seated? If you still suspect a vacuum leak but can't find it externally disconnect the power booster (if you have one).
