Eddy Carb Issue #985470 05/03/11 03:43 PM 05/03/11 03:43 PM

After about 4 days of sitting, the carb doesn't have fuel coming out of the squirters when I pump it to start the motor. I have to spin it long enough for the fuel pump to fill the bowl- then it fires right up. Is there a common place for these carbs to be losing fuel this slowly? It doesn't seem to be a problem until about after 3-4 days. Thanks fellas

As the gas heats and expands when the car hotsoaks, it will allow some of it to push back to the tank. Yes, an electric pump will solve the symptom, but a return line will save some of the fuel. I saw a realy explanantory magazine article on this a few years ago, a netsearch might find it for you.

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.

I've been running the same carb for 20+ years. It's a little tougher to start with todays blended gas. When I'm at home with the car I don't used blended gas. Makes a big difference for me. When I'm out of town with it I have to buy blened gas. I just started my 74 with a 1405 600 eddie carb on it last week one day. The car has sat since around Nov last year. It fired up after about 8-10 seconds crank time, just like always. This is the same carb that sat all through the 90s and maybe getting started once a year, haven't even rebuilt it.

They don't suck, they push (which really sucks!). Has anyone solved this or has anyone come up with a "in tank" electric pump like with modern cars that doesn't require cutting the tank apart?

Mount it on the fuel line, inside the frame rail midway between the engine and the tank and it will always be below the tank level. To answer your question- the fuel is evaporating out of the float bowl vent- which is on the top of the carb. And- use a think base gasket- the black rubberish ones work well, or a phenolic one is ideal. Eddy's don't like heat- it will evaporate the gas FASTER if you don't have one. Yeah- modern gas is the worst! Thank You Mr. EPA.... If your a holley guy your going to be amazed how easy it is to work with the Eddys. Much much easier to tune/alter for your application. Good Luck, CC.

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. 75 Duster, 451 10.87 @ 123.58 NA 97 Z28 6sp., 12.01 @ 115 on a 100 shot 71 Swinger. 360 magnum. 12.58 @ 105 78 cutlass, 469 BBC. 12.70 @ 108 on street tires. http://www.youtube.com/watch?v=Z2kqNmMfheU

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

I've had 2 different Holleys on my BB, a 750 vac sec and a 800 double pumper. The last 2 winters(one with each carb)I parked the car in Oct-Nov and didn't touch it till April. Both times I popped the air cleaner,looked down the carb throat and sure enough....squirt,squirt. Few cranks and it lit right up!
