With the vacuum line off of the distributor your idle rpm should be at 6 to 700 rpm and the initial timing at 8* to 10* then when you rev the engine to about 3,000 rpm you should have about 38* total advance
still having the hesitation. I also put hose clamps on most of the vacuum lines that I suspected were leaking. the "carb cleaner" spray test was making the RPM jump about 50-100rpm pretty much anywhere I sprayed on top of the motor.
Keep checking, you still have a vacuum leak
I'm not getting any readable vacuum from the line that goes to the vac advance at idle. there is a little plastic cylinder in line... i'm assuming some kind of check valve... does this need to be in here?
The carburetor has a built in ported vacuum passage which governs the amount of vacuum the advance gets and there should not be anything between the carb abd the advance.

And you are not suppose to, if the carb is adjusted right. You get vacuum at the ported vacuum fitting on the carb after you crack the throttle about 1/16 to 1/8th open.
