Carb trouble...Should I Switch to an Edelbrock?

[IDC10]

I'm running the original 307 on my '68 C10. The motor was running nice and strong, until one day it stalled out and would barely start and run. When I opened the hood, I found gas all over the intake manifold.

I have a Holley 4160 carb. I removed the front bowl on my carb and cleaned out the needle valve, then reset the float level. Then I started having issues with severe hesitation and stalling. Checked the accelerator pump, and eventually replaced the power valve.

When I replaced the power valve, the motor idled great, and initially seemed to drive great.... after a mile or two, the hesitation and stalling started again, barely holding an idle, and I could barely make it home.

I have a Summit clone of a GM HEI distributor. Replaced the ignition control module....exact same behavior.

Fuel pump doesn't even have 100 miles on it and the motor is getting plenty of fuel...and I can see the gas in the clear fuel filter next to the carb.

So I'm thinking I have to completely tear down and rebuild a carb that is only a few years old and hasn't seen a lot of use. I want to throw it across the shop and just get a new carb.

Are the Edelbrock carbs less temperamental? From what I'm reading about, they seem to be simpler. I'm looking at a 500 CFM model 1403. I need something that is going to be solid and reliable.

Chances are it has problems because the ethanol in the gas is toxic and attracts water. You may have bad gas as well.

I'm using non ethanol gasoline....from a fairly new gas station.
