Hard cold start- lack of fuel- UPDATED
I "threw in the towel" on my 67. I brazed a 1/4" line into the face of the tank, after filling it with CO2 from my MIG bottle, installed an electric pump at the tank, and made a "vapor return" system using a Wix 33040 (5/16) or 33041 (3/eights) which has a built in 1/4" return port with an orifice inside.
You do not HAVE to remove the mechanical pump
Last winter we had many nice days with no rain and dry streets when I drove the car. I could get in there, turn on the key for 3-5 seconds to run the pump, hit the gas 3, 4 times (no choke!!!) and it's runnin'!!!! I'm talkin about 20*F days here!!! The car might have sat for two weeks or more. waiting for that one nice day.
I use an Edelbrock "red" pump, and made auxiliary grommets to quiet the thing down. If I was to replace it I'd try a Carter
