That what 'mfg' said....... and I'll bet that if you install a manual choke, your experience will be much better. I'm not familiar with an Edelbrock electric choke but the ones I had were energized as soon as you turn the ignition key on. If the engine doesn't start right away, the choke continues to open and you're basically out of options, unless you pour some gas down the carb or turn the key off and wait 15 minutes for the choke coil to get cold again...
A long time ago, I had an electric choke kit (1967) that was wired to one of the exhaust manifold bolts to sense engine temps and that would be great for today's cars as it would emulate the original auto choke process.
BTW, I saw your car in the Gilmore just last June. Very nice car and a great place..
