Edelbrock 1406 Not Pulling Fuel into Carb

Jimbo_74_Duster said

Hey All,

I'm sure there is something simple and obvious I'm missing but I am still stumped. Long story short, after putting the carburetor back on, I wasn't getting any fuel into the actual carburetor when pumping the gas. Not even into the fuel bowls. I disconnected the fuel line from the Fuel Inlet and manually sucked fuel from the tank to make sure it wasn't something down the line towards the fuel tank and that was all good.

I then, manually filled the bowls to see if the plunger would do the pump shot and that all worked fine as well. I also made sure that the floats were NOT stuck up and I actually blew air into the fuel inlet to make sure that circuit wasn't clogged. Is this a sealing issue between the Air Horn and Body Assembly? Theoretically speaking, if I manually pump the plunger, shouldn't I feel a suction if I place my finger over the Fuel Inlet? Because I'm not feeling any suction.

The grooves on the Air Horn, that push into the gasket, are worn down pretty bad, could this be the issue? In the photo I attached, the area circled in red is where the groove is warn nearly all the way down.

Thanks for the help.

I have the exact same problem, or worse. Last year the 440 in my motorhome, which always started fine before with no issues, suddenly would not start without giving the carb a prime of gas. It would kill trying to get it out of the yard, but once on the highway ran perfectly with no issues until I stopped. A new fuel pump, as that would seem to be the problem, even though the other one was only a couple of years old made NO difference. The newest one is pumping fine, but no gas is getting into the carb, bone dry. And this is after I paid over $400 this spring to get the get the carb rebuilt. Ran better, but still needed a prime to start, even if I just shut it off and tried it again, immediately. Took it back to the shop and they cleaned it again but said they could find no issues why it was not getting gas into the carb. It is ridiculous, plenty of gas and pressure into the inlet, which I have also checked for problems and found none, but not one drop of gas seems to be in the float bowls, and all the pumping of the accelerator, even while cranking it over, provide no mist in the carb, no nothing, dry. I hate mysteries and am getting no answers on what the heck is going on here. The repair shop worked on it for free the 2nd time but said if I brought it in again I would be charged. Not happy with this Edlelbrock product at this point, and can't afford to buy a new one. I too am stumped.
