I have an 86 IROC with an LG4. I had been having problems with the engine lately, sputtering every now and then and the like, stalling, but they had gone away, and I usually give the engine some time to warm up before I drive it.

Tonight I had stopped at the supermarket. When I came out (engine warm), I started the car...started up fine, then when I started accelerating, it just started sputtering, losing power, and threatening to stall. I managed to give it some throttle and limp back to my apartment. When I looked under the hood, I opened the air cleaner and looked at the carb...GAS puddled on the throttle plates...engine stalled, was so bad there was a fog of fumes around the primaries. I let it air out for a minute or two, then pushed the pedal all the way down and cranked till it started...sputtered for a little while longer and then ran...rough, but close to normal.

I had the whole carb rebuilt last winter. I'm wondering what can be causing this. Someone suggested something might be gummed up in my floats, letting gas spill into the carb. How do I fix this? Does this sound like what it is?

It seems like at any rate I may have gotten a shoddy rebuild. Any suggestions? Can I do something easy to correct it or do I have to have it opened and rebuilt AGAIN? If so, can anyone recommend a place? (BillK I know you're fairly close to this area...do you know anywhere nearby that I can trust?)

More info...I started the car up this morning...ran fine. I'm wondering if it was a fluke thing or if I should worry. I mean, is it possible some dirt or something got jammed in the float needle and now the "stone is passed," if you'll excuse the metaphor? Could it be that there's something in my gas tank? Last time it was doing this I checked the fuel filter and it looked fine. Where do I look for a problem?

Thanks again,

It sures sounds like the float stuck or as you said might have had some contamination. If it does it again, you will have to clean it out.
