I finally have found the time to look closely at my 56 Fairlane's engine.
It has an Edlebrock carb, but still has the loadamatic distributor.
The engine/car is a real dog
The distributor appears to have a double diaphram. Questions:
1) Is that correct for the engine?
2) How can I check this thing? I have a vacuum pump/gauge

Any help certainly appreciated

Regards to all
Jim
