Thread: edelbrock carb problems

Tweet

I'm trying to run my engine and everytime it fires up it runs for 5 seconds and drys up the bowls before the pump even has a chance to get pressure to it.
Then I have to disconnect the line and fill it by hand again. Then the same damn thing happens again.
I can't even describe how frustrated I am right now.
Does anyone have any idea why this is happening? Shouldn't the bowls be able to run it for at least a minute before going dry?
Do I need to take this stupid thing apart already?

I just took the top half off the carb so I could check the floats and make sure something wasn't sticking. Before I put it back together I filled the float bowls. I put the top back on, started it, it ran for 5 seconds and then died and wouldn't start again. I took the carb apart again so that there would be no question about what was going on in there.
The bowls were already empty.
The bowls on edelbrocks aren't that big, but STILL, what the heck is going on here? 5 seconds.

maybe its the brand of carb

yeah, that's what I'm starting to think.
so far I'm not very happy with edelbrock.
this is bogus.

i have use a lots of them a they work very good . some thing is not rigth but you know that .is the power needle in the carb is the set up springs right it are the floats set to hi? two thing they dont like to much fule psi no more that 5 psi and to hi seting on floats

Try this, unhook the coil wire, or the power to the coil and crank the motor for 5 to 10 seconds, that should draw fuel up from the tank and into the carb, if not then the pump is bad.

No carb will run without fuel. Pressure up your fuel tank and blow fuel up to the carb if the pump doesn't want to prime.

I have been filling the carb with fuel each time. I just disconnect the fuel line and hold it up and fill it with a funnel until no more will go in. Then I start it and it runs dry in 5 seconds.
The needles are in there and they have the factory step up springs. The floats are set exactly as the manual says they should be set and nothing is sticking on them.

I am going to replace the fuel pump, but regardless, it shouldn't be running dry that fast should it?

oh yeah, and I am using a pressure regulator set at 5.5, just like the manual says.

I have no idea what's going on, but I just wish my engine would start when I turned the key and then keep running. My lawnmower starts on the first pull for cryin out loud.

i know how to fix it

how?
with a sledge hammer?

no with a holley but that hammer might work to

come on hammer heads i have used the edlbrocks on blower setups used them on street rods with 1/2 the time it take to get the gaskets of a holley to get edlbrocks running rigth. get a new fuel pump and check gas tank vent i don not know how long it take to run dry the bowls but i would say not much bowls are smaller then a holleys

I am not pulling fuel from my tank yet, I'm just using a can right next to the pump, so it's not a venting problem.
The first thing I tried when I took the top of the carb off was blowing into the inlet. It went in fine through both floats and they closed off properly when I flipped it upside down.

I don't have a pressure gauge so I don't know what it is reading, I just have a pressure regulator on there now.

The first thing I'm gonna do monday is get a new pump, I actually just switched my pump but I used one I found in my closet because it looked in good shape. Bad judgement I guess.

The thing I'm most boggled about is why it's using up those bowls in a matter of seconds. I'm running a 226 @ .050 cam, could the vacuum be too low for the step up springs, so those needles aren't getting sucked down and letting too much fuel in?

if theres is no vacum the needles will stay up on the rich mix and run the fuel out??like a blown power valve on a holley this will dry out the bowl on a holley and make it run rich

it sould be on the idle circuit but. with the metering rods up this could be something to look at and try a electric fuel pump or a new pump and like denny said do you have the fuel pump rod in it/
