When money puddles...

Me and my brother went out to get a bite to eat today. It was a little tavern about five minutes from my house, so we get in my truck and take off. Since it is such a short drive my truck didn't get a chance to warm up, but I just can't resist kicking in the 4-barrells anyway. It sounds so good. Anyway, as I am pulling into the parking lot I notice my RPMs start to drop, I kick the gas pedal a bit to try and keep her going, but it's no use. She's dead. I sit there and crank, pump the gas once or twice, she takes a bite, but doesn't start. I figured she probably just flooded, so I hold the pedal all the way down and try to clear her up while cranking. Well, my battery isn't very good anyway, and she starts cranking slower and slower, so I give up. I get out and pop the hood, and try to see why she stalled. Looking around a bit, I finally see puddles of gas on my intake on either side of the carb. I open the butterfly and see gas pooled up inside my carb. I figured maybe she just needed some time to clear up, so I go inside and eat. When I come back, the puddles are gone, and so I climb in and try to start her up. No gas, just turn the key. She cranks and cranks, but the battery starts to run out again. I look again and there is gas dripping and forming more puddles on my intake, but this time I didn't even touch the gas pedal. What is going on? I am assuming that something is stuck open, and that it is just pouring gas into the carb when I crank the engine, but I know jack about carbs. If you guys could explain, in laymens terms, what I should do I would appreciate it. I have a stock Goodwrench 350. After I get a tow home from my dad, I crank her again, no gas, and gas begins to drip and form puddles again. She sat for about 2 ours before I towed her home. What should I do?

Thanks in advance for any and all info.

What kind of carb are we talking about? Sounds like what you said, when you are cranking, the fuel pump is pushing fuel to the carb and it is running out. Could be the connection to the fuel line, a stuck open needle and seat (my bet) or a leak from somewhere else on the fuel bowl (like a site plug on a Holley).

Have someone crank it and watch where the fuel comes from, that will be a good start.

yeah, sounds like needle and seat. Tap on the float bowl with something and see if that knocks the offending piece of dirt, probably....loose.

Well, after charging the battery over night, I put it in, and my truck started fairly easily. I let it warm up, and took it for a little spin. Everything seems to be working okay. It didn't stall or anything. However, after I got home and shut it off, I did notice that the base of the carb was wet looking. I'm not sure if that is from yesterday, which I doubt, or if my carb is still leaking from somehwere. I guess I'll just keep an eye on it, and hope everything will work out.

From past experience, if it did it once, it will do it again. If I were you, I'd go ahead and do a rebuild on that carb. Kits are cheap and it's a fairly easy job.
