I little while ago I installed a Edel. 750 and now it takes quite a few turns to start the car ONLY when cold. After that it starts right up. It seems that there isn't enough fuel in the bowls to start it. Although I do hear the carb squirting out....I then installed a heat shield thinking that the fuel was boiling over, but didn't help. Does my fuel line need to be adjusted in such an angle to keep some fuel in line? I have a glass fuel filter, and after a little while the thing empties back down and into the mech. fuel pump.

Any ideas?

It sounds like the diaphragm in the fuel pump is going bad. It should keep the fuel from reverse flowing. Make sure you don't have a leak between the carb and the pump. If you don't start shopping for another pump. Fuel will evaporate out of the carb, but if you're starting this thing on a regular basis there should be enough left in the carb to get it started. Next time you go to start it take the air cleaner lid off and work the throttle by hand and see if there's fuel squirting.

The pump is a Holley pump I installed last year. There is no leak fron pump to carb. I did verify, there is fuel squirting into the carb before starting. Maybe not enough? The car may sit 2-3 days sometime, but even when it sits for 24 hours it has a hard time starting cold. Strange because it did not happen with my Holley VS carb, same setup.

There's a good chance the Holley had a larger accelerator pump capacity. I have a 650 double pumper on mine and have to give it 3 or 4 pumps to start it after it sits a few days.
