Getting fuel to the carb

I was trying to fire up my BBC for the first time today. Everything seems as it should, however it seems to be taking some time to get the fuel to the carb. (Mechanical Pump) I am asking while my battery charges because it has been drained from cranking. I should say it is not a new battery, but not a junk battery either. My buddy says it's such a long car, it's going to take some time. Recharge the battery and keep trying. Any thoughts?

When I first started mine I had replaced the entire fuel line on a resto., I removed the plugs to take the compression off of it so it would'nt strain the battery; disconnected the carb fuel line and cranked it till I got gas to the carb. Remember to pull the 12V so no spark will ignite fumes.

You could also fill the fuel bowles to get it started until the line is full. Mine took several fills.

I think i figured it out. "expert friends" claimed a small block fuel pump is the same as a big block. I have since learned they are different. I will be changing tomorrow.

When I restart my classics (with carbs) in the spring, I pour about 1/4 cup of fuel right down the carb throat. The engine will catch quickly, pulling gas from the tank. It may stall, but will restart very quickly with full fuel pressure.

Two doors, four doors, wagons, and ragtops.
