My car is carbed. Sometimes I can get in it, press the gas a couple times and it start right up. Most times I have to hold the gas pedal to the floor while I crank to get it to start. After driving for a little while, I can turn it off, wait a couple seconds and start it right back up. If I go inside somewhere for a decent amount of time it goes back to being hard to start. It drives fine. Any ideas on what would cause this? Carb is an Edelbrock 1406.

 

think you prob need to clean your needles.. maybe time for a rebuild of the carb...

 

The carb is brand new.
