Carb. Fuel Loss When Not Used

mrud · #1 (**permalink**) 08-29-2006, 07:36 AM

I have an 830 Holley on my 427SO FE. When the car sits for over 2-3 weeks and I try to start, Lose fuel and have to prime carb. Is there a quick remedy for this other than installing an electric pump. What is the best way to prime the carb other than putting fuel directly into the barrels which is not the safest of ideas?
Thanks

Mike,

That's pretty unusual. It sounds like you're drawing air or have a small leak upstream, or the carb is leaking. Two weeks shouldn't be enough time for most of the fuel to evaporate from the bowl. Also, the check valve in the pump may be leaking back.

Make sure all the fuel line clamps and the junction (inside the frame rail, approximately under the seat) are tight.

Mike,

You really have problems elsewhere because you shouldn't have to do this, however I've a Speed Demon Carburetor and this was taken verbatim from their Instruction manual regarding priming the carb.

"The best method for priming an empty carburetor
requires a fuel compatible plastic squeeze bottle,
such as BG Part # 130041. Fill the bowl through
the vent tube until fuel is visible in the sight
window. Depress the accelerator pump levers
once or twice until fuel can be discharged from the
pump discharge nozzles....."

Bob,
The Car is kept in my garage and I see nothing on the floor. Maybe just too hot in the garage. Once I prime the carb, engine comes immediately to life. I don't mind priming.
Regards
Mike

Something is leaking. Turn on the ignition. Slowly press the accelerator pedal to the floor and release. The gas from the accelerator pump is enough to start the car. I have gone 4 months without starting my Cobra, and it starts up immediately.

Fix the leak(s). Squirting gas in a carb is dangerous! At least using a dropper and putting it into the bowl vent is safer, but the gas in the accelerator pump should not evaporate in 3 weeks. No way!

GAsoline evaporates in high temps. Two to three weeks doesn't seem like that long of a time, but how hot is it in your garage. Even if your floats are low there should still be a shot in the accelerator pump. I had a truck that did the same thing and it was a bad diaphram in the fuel pump. I believe you has a bad pump thereby causing fuel to flow back instead of forward.
