Subject: Edelbrock carb problem
I have an Edelbrock 600 cfm carb, #1400 with electric choke. It seems the accelerator pump is not doing it's job. I can only start the engine if I prime the front 2 barrels with a mall shot of gas. Once it is running, everything seems normal. Am I correct in assuming that pumping the accelerator should squirt jets of gas down both throats through the 2 small nozzles? Doing so results in a small dribble of fuel out of them. I pulled the carb apart and the accelerator pump chamber seems a bit corroded and pitted. I cleaned it all up and reassembled with no improvement. Will a rebuild help? This daily priming is for the birds!

I know that Holleys give you a big squirt and I suspect your Edelbrock needs a kit. Most carbs require a squirt for starting, you shouldn't have to pump but you need to at least push the pedal once before starting especially when it's cold (this sets the choke).

Are you sure that the carb is not leaking down? Are the bowls staying full of gas? My Quad. has this problem & was told to reseal the well plugs. Haven't tried it yet.

If, after you get it started, everything is ok then I doubt that the accelerator pump is bad. If it was the problem, then the car would have a real bad stumble every time you tried to leave a stop light, etc. It could be that you have a small hole in your fuel pump diaphram that allows the gas to drain back down the line. I know that the quadrajets have problems with plugs leaking, but I've never heard that about the Edelbrocks. Anyway, check your fuel pump pressure, and see if your oil dipstick has a slight gas smell to it. The fuel pump can leak into the oil pan, and if it is a small leak you might not ever notice without checking. Give it a check and let us know what you find out. Good luck.
