Its funny alot of you say its the fuel, hmmm, i remember having the same problem with any eddy carb i ran as far back as the early 90s, after a good week the carb would damn near go dry, Whats ironic is i never had that problem like this with any holley i've ever used & i've used alot of them (unless the gaskets were leaking), my last 3 holleys were on my 360 magnum just last year, that car would sit a good 2 weeks at times (summer or winter) didn't matter on todays blends, the bowls would always hold plenty of fuel  .
I do agree todays blends have a lower boiling point, but i don't think by much.
holley's have much bigger fuel bowls and they are hung futher away from the intake.

It's not just not just a edby/carter carb problem it's the current BLEND and all carbs. An electric pump would be a way around it , you turn on the pump and it fills the carb , should light right up .
I did what johnrr suggested and works great!
I'm considering doing this on any car I have now wit ha manual fuel pump , I don't trust the ethanol in the fuel and that it could eat thru the rubber diaphragm and fill the crank case with fuel. 
you'll be fine. you never drive your car anyway 
But when I do drive them my engines stay together ...

Thanks guys. My dad has a cheap parts-store electric fuel pump sitting on his shelf. Maybe I'll just mount it in line and use it to start the car. Maybe I'll try a thick carb gasket as well. I'm just glad to hear it's a common problem and that I don't need to rebuild the carb.
Thanks guys!
One thing to check/watch out for is fuel flow with the electric pump off. Some will let the regular fuel pump pull through when electric power is turned off and some won't. You may need a bypass line around the electric fuel pump with a check valve to prevent backflow.

A small electric pump is not gonna flow enough on the suction side of a mechanical and when you turn it on it's still not gonna flow enough unless you have a large electric, then there's no reason to have mechancal.
A small electric pump to prime a carb is not worth the hassel. imo

I agree , I would ditch the mechanical pump all together .

that's because you aren't trying hard enough.
If I remember the scenarios correctly anything below 3000 rpm is all it would take?

could have been the 8-10 romps I took before that..... No idea why the valve came apart, could have been a cam failure, but I didn't hear any noise before hand...
anyway back to the topic.
Just leave it as is. Try a spacer or FAT gasket and roll.

Thanks for the input guys. I guess it's not that bad of a problem. When it's dry, it takes about 8 sec. of cranking to fill the bowls.

CC, what brand/model electric 'booster' pump do you recommend? I have the exact same issue with my set up (318, Eddy600, the regular fuel pump) but was afraid an electric would push too much pressure to the Eddy carb. To you keep the stock pump with the booster?
Thanks,
Jon
Hi Jon,
Currently I am running the full-on Carter Electic- the kind they have been making for generations! It provides between 5-8 psi constant, with good flow. BUT- it is NOISY. I did it because I wanted to be sure that I had good flow, and I plan on a BB conversion at some point in the future.
I also retained the factory mechanical pump- partly to act as a 'regulator' and partly so that if the electric ever fails, I'll still get pressure.
Now-
This is something to remember-
Back in the 80's Chrysler has a lot of issues with the M-bodies and vapor lock. This is due to a number of factors, but thier answer was a recall that included a small inline electric 'booster' pump. This was something they did when a customer complained.
Sooooo...to solve this issue, you can really use any small electric booster pump- like this or something similar:
http://www.oreillyauto.com/site/c/detail...5&ppt=C0128
This would provide all the pressure you would need to fill the fuel bowls before start up. You could even put a switch on it- turn it on a few seconds before start and then shut if off after.
Up to you....
Hope this helps,
CC.

It'll take a couple of hours it takes to install an electric pump in a professional manner, and big pumps are noisy.
The extra seconds it takes the mech pump to re-fill teh bowls is also time for teh oil pump to re-lube the engine.
