'71 350 C10 only firing when gas dumped into carb ...

[bessie66]

This is, so far, a month long issue and my longest yet with any classic i've had the pleasure of owning.
Background: '71 C10 lwb 350/th350, performer intake(spreadbore), eddy 1405 w/ spreadbore spacer, holley fuel regulator/gauge(set to 4.5lbs), HEI.

It has been a full-on-war. The other day I was taking a trip around the block when the motor bogged(immense power loss) about half way around the block. If I took my foot off the gas it would die. I fired it back up and forced the son a bit*h back to the garage by throttling it to keep it alive. I assumed it was the eddy 1405 since i've nothing but issues with it, even after the rebuild it's been inconsistent. Example: it has idled perfect one day and not worth a damn another day. The truck was dialed-in awesomely after the performer intake and carb swap, then these issues have been randomly plaguing the truck since.

I went out this morning to crank it up.. nothing. So I decided to put "ol faithful" the quadrajet back on. I removed the spacer and put the quad gasket(the thick heat insulating bad boy) back on and It fired right up, but died. Hmm.... tried to crank again, and nothing. I poured gas into the quad and it fired right up, burnt the gas up and died. Sh**. I removed the fuel filter and the regulator(i didn't need or use the regulator with the quad before tIhe swap), no go. BTW the fuel pressure reading is 7-9.

i feel I should mention I had NO issues while running the stock intake and quadrajet setup; it was a majestic enterprise.

I hate to sound like I'm about to throw in the towel, but i'm at my wits end. We are about to move and I'm grumbling at the possibility of having to pay to trailer it. The recent birth of my son has limited my garage time substancially - patience running thin to say the least.
