To start my 78 with a (400 cid engine and 750 cfm Thermoquad), I simply press the throttle to the floor once and release before I crank the engine. This works every time. Hot, cold, summer, winter, it doesn't matter. It starts fast and runs well every time. Depressing the pedal does two things, it does indeed squirt a little bit of fuel from the float bowls into the throttle chambers and it also allows the choke to set in the event that the ambient temperature is low. ----- Original Message ----- From: "Rob P" <fristpenny@xxxxxxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Sent: Friday, May 17, 2002 7:37 PM Subject: IML: pumping when starting Ok You pump the pedal to start a carb car. Jealous of you EFI guys. I never really do it more than 3 times & some of my cars are run on old stale gas & not started for months at a time. I am very lazy. Pumping the pedal does not get gas to the carb from the pump, or the pump from the tank. Right? Unless the motor is turning the pump doesn't operate & it doesn't move any fuel from tank forward. My understanding is that pumping the pedal just dumps some fuel from the floats into the heads, priming the motor to start. Is this correct? I don't really know much about the accelerator pump. 20-25 pumps seems excessive to me. Rob
