How many pumps?

When cold, once all the way to floor to set the choke, then turn the key and it fires right up. That's when driving it every day. If I let it sit for several days, I have to pump twice then hold the throttle down about 1/2 way.
When warm, most of the time I don't have to pump at all but sometimes it takes holding the throttle about 1/2 way.

Never pump the gas pedal. I have an Aeromotive Street and Strip electric fuel pump. When I hit the ignition key position, the pump turns on and at the same time the starter turns over the engine. The engine might make a couple of rpm's but then it fires up.

One....just to set the choke and pump some fuel in the intake. Wait 3 seconds and start it. If you need to do more than that, you don't have the choke set up right...or the accelerator pump isn't working properly...
or you have a Holley!!!!

OK, OK.... that was an attempt at humor -- not a vendetta against Holley carbs.
That's the way all carbs should work, anyway.

I mounted a chokeless Demon double pumper on mine. Same basic design as a mechanical double-pumper Holley. Fed by a factory-style mechanical fuel pump and 10 degrees of initial timing on a Comp Cams Magnum 292.
1 pump cold and lightly feather the throttle after start to clear its throat. Part throttle to none warm, gets mine back to idle.

cold: one pump before I turn the key, one while I turn it to start. It turns over for maybe 2-3 seconds and then fires up.
hot. just turn the key and it roars to life
