Battery light stays on

lights must be connected to a circuit that does not run thru ignition switch.

I would google it, or call a parts store and give them that code.

you may have a vacuam hose off somewhere, else adjust the throttle plate stop on the carb where the linkage comes to rest

the pistons are absorbing too much gas flooding the thing I think.

Hope this helps (remember to rate this answer)

what you could start with is checking to see what trouble codes are being logged for this vehicle...if the engine light stays on, it means the ecu is registering a fault......by the means of a trouble code...now the trouble code doesnt tell you how to fix it, but it does give you the direction to go down...judst wondering if you have tried to obtain the trouble codes

Start with dirty fuse connection and then look for mouse wire damage

You would get the correct carburetor instead for electronic computurized controlled carbs will not work on a 1981 Corvette

At first blush, sounds like corrosion on the battery cables either at the battery or at the other end at the alternator or starter. There are several sprays at the auto parts store that will clear the corrosion but the best way is to remove the cables and clean both the cable ends and the posts. Once you're able to rule out the cables/connections having the charging system checked would be next point of order but its more likely to be the cables. A car that won't run on it's own isn't getting enough power from the alternator so I'd check the negative cable first.

sounds like you have trash in carb bowl, you need to remaove the carb and cleanit out and try again
