vacuum advance

This is all in an attempt to keep the car from missing during coast conditions. Acceleration is good, but maintaining constant speed, the car misses a lot. Doesn't really low you down, it is just an irritating pop-pa-pop out of the exhaust.
Also looking into getting a brand new distributor. The current distributor looks relatively new and clean, but I don't know if it is causing the trouble.
I am running an electronic ignition. The control box is just a year old and the wiring was new then too, just the dist was used.



If you have surging at part throttle, you can adjust the diaphram in the vacuum advance with an allen wrench in the hose nipple by turning clockwise (I think).

It's probably set at midway and I think there's approximatley 12- 14 total turns available.

I'm not sure about the popping when coasting, that may be a lean carb or an exhaust leak sucking in fresh air.
