Default Carb not getting fuel inside

I have a Holly street avenger 770 on my 383 stroker. The car was sitting for about a year, it has a racing fuel cell with the foam stuff inside. I just had a shop put a sweet exhaust system on and when I fired it up to drive there it stalled a couple of times. When I drove it home it stalled at a stop light but fired right back up. I went to start it today, 1 week later, and it won't start. The engine turns over, and there is plenty of fuel in the bowls. I took off the float setting screw to see that there was fuel in the bowl and there was. I sprayed carb cleaner and it ran for a couple of seconds, but stalled.

Any ideas?

when you open the throttle by hand do you see fuel shooting out of the sqirter. do you have a fuel pressure gauge on it? what is the pressure set to?

I'm guessing the jets are clogged? When I went to take off the fuel line it squirted all over the place. What is the easiest way to clean this carb?

when you pump the throttle and no gas shoots out the sqirters then it wont start because theres no fuel in the motor. thats the first prob i see. are you running a mech pump or electric. there are 4 long bolts at the end of the float bowls. take those out and clean the bowls and metering blocks. if you have a compressor you can blow air thru the holes in the metering block to check if there clear. it sounds like a fuel delivery prob to me but i would take the carb apart and clean it then you know its not that. if you were closer i would come take a look and help you figure it out.

I'm having a similar problem..... I Think. I also have a street avenger 770 on my 71 454 and my car died last time I drive it. I was able to pull over and then it fired right back up. I haven't had time to troubleshoot it yet. But I have a fuel pressure gauge and I noticed once that the FP was like 1/2 psi. It has a mechanical pump. I fired it up over the weekend and it was reading 7 psi. I was going to start by checking the pump and filter.

If the fuel bowls are filling then the fuel pump would seem to be ok. You could disconnect the line somewhere, stick it in a bucket and crank the engine to see if gas comes out.

If the gas was sitting in it for a year I would think more along the lines of varnished needle/seat assemblies or possibly a faulty accelerator pump (both of these conditions would keep the squirters from squirting).

Yes it could be the accelator pump, mine did the same thing and that was the problem.

This is going to be a fuel problem. Fuel starts to go bad after about 3 months. Gasoline is highly volitle and all the good stuff evaporates right away, leaving you with sticky goop that plugs jets and makes needle and seats stick together. You'll need a couple of cans of carb cleaner, safety glasses and bowl gaskets. Remove the float bowls, clean off the needle and seats, clean out all the jets, drain the fuel tank, add Checron Techron and hope for the best. This same thing happened to me after sitting for less than a year, gas tank is still out as I am repairing wiring and fiber optics in the gas tank area. I need to get my baby on the road and not let that happen again.

good idea, but you might as well rebuild it, however if it's new,
the throttle pump is probably stuck. good luck (:

My 74 sat for ~5 months and I had no gas being fed to the carb. Feared my fuel pump diaphram cracked . . . But I sprayed starter fluid in it 6 or 7 times trying to get it to prime and fire up and got nothing.

I let it sit for 2-3 hours and just went back out to take another look and moved the throttle linkage and BEHOLD, the jets squirted gas!! So the starter fluid must have helped unclog the jets.

If I were in your situation, the first thing I would try is to remove the accelerator pump nozzles (one screw, use a magnetic screwdriver so ya don't drop it down in the carb, if ya do, the throttle blades will catch it, and you can get it with a magnet) and spray some carb cleaner down in there, (there are check ***** and stuff down in there, be careful not to blast them out with the carb spray!) clean the nozzles with the carb cleaner, re-assemble, and try it out. If that doesn't work, yer lookin' at dis-assembleing and cleaning the carb.

I use Stabil when I store my 'vette for the winter, and I've never had a problem with bad gas come springtime.

Currently replacing my mech pump with an electric, should be all back together tomorrow. My car has not been liking the ethonol gas so hopefully this along with a complete carb cleanout will be the answer
