On the 231 in my '83 when I flood the engine, even the smallest amount, it will never restart without pulling the plugs and letting it sit. It's impossible to clear it with the pedal to the floor as you would normally, it'll sputter forever until the battery dies. I've been stranded a couple times because of this. The carb did this before and I find now after a complete rebuild too. Never had this problem with a V8.. which I would swap in and ditch all the smog junk. Any suggestions?
231 floods out badly

next time remove the air cleaner and cover the carb opening with rag and then start it...it sounds like the float needs adjusting or the carb needs a rebuild

If it's already flooded then covering the carb with a rag and trying to start it is gonna make it worse.
Checking the float level is a good idea, and when is the last time it had a tune up?
When it is running does it run good?
Make sure the choke isn't sticking.
I'd say hook a chain up to it and give it to someone that owns a boat :wink:
If you don't have to worry about emissions and funds permit, I would be looking for something with 2 more cylinders to drop in the car. Even the good running 231 V6's I've had were complete dogs.

That should be a DualJet which is the front half of a Q-jet. First make sure the float level is correct for your application, and that the pump rod is in the INNER hole for a shallower pump shot. Then adjust the choke unloader so that when you push the pedal to the floor the choke opens up to clear a flooded condition.
it does work. basically the lack of air flow prevents it from pulling fuel, so it doesn't get worse, and since its (sort of)pulling vacuum it vaporizes the fuel, which allows it to be pushed out of the cylinder. but it won't work on badly fouled plugs.pontiacgp said:
in addition to what they said, check the needle and seat, if theres dirt in there they won't seal and the fuel pump will just push fuel through.

Hmm this is one I'd have to see to believe, or it would take a pretty convincing explination :?
How is holding a rag on the air horn any different than using the choke? A restriction on top of the carb is going to create a vaccume and cause fuel to be pushed out of the float bowl (by atmospheric pressure) through the main circut and into the engine.

even with the choke flap closed there is still air getting through, with a rag there is no air getting drawn through the carb. As for a detailed explanation I think megaladon6 gave you a great one but if that doesn't convince you then I guess you'll have to wait until you see it done
