Fuel flooding the carburetor 1985 prelude my prelude is pumping gas to carb and won't start to much fuel what can I do to fix and how much will it cost the engine runs great until I had this fuel problem it has twin carburetors .

Check your float level in carb. & test the valve with the float, check your fuel filters and check your fuel line from the tank or check for dirt in base of tank, lastly check your HT leads to plugs

there is probably a filter screen where the gas comes into the carb. Remove the gas line and the nut it screws into on the carb to find the screen.

If it won't start, then pumping the gas and using carb cleaner may make it worse. Carb cleaner is not the same as starting fluid. It will make the engine harder to start. If it's flooded, then pumping the gas will only flood it more. If you need to de-flood, then press the accelerator pedal ALL THE WAY TO THE FLOOR and HOLD it there while cranking. Don't pump it.
Have you looked at the top of the carburetor while someone cranks the engine? Does the choke close when you press the accelerator for the first (and only) time? You state that you replaced the choke; do you mean the electric choke spring? Is it adjusted correctly? You need to know the choke setting for it to work properly.
Then again, it may have nothing to do with the choke. Do you have spark at the plugs? Have you checked the fuel filter?

It sounds like you are experiencing a problem with the Rochester 2GC carburetor on your 1957 Oldsmobile. The issue you described, where the engine is difficult to restart after it has been shut off for a period of time, could be caused by a number of things.
Here are a few things you can try to troubleshoot the problem:

1. Check the fuel level in the carburetor bowl. If the fuel level is too low, the engine may not start. Make sure the fuel level is at the proper level and that the bowl is not leaking.
2. Check the float level. The float in the carburetor controls the fuel level in the bowl. If the float is set too high, it can cause the engine to flood when it is restarted. Adjust the float level according to the carburetor manufacturer's specifications.
3. Check the fuel pump. The fuel pump supplies fuel to the carburetor. If the pump is not working properly, it could cause the engine to flood or not start at all. Test the fuel pump and replace it if necessary.
4. Check the fuel lines. Make sure the fuel lines are not clogged or damaged. Replace any damaged or clogged fuel lines.

I hope these suggestions help! Let me know if you have any other questions.

This is usually caused by a stuck float valve. Tap on the carb with a small hammer or screwdriver at the fuel inlet area and the valve may reseat. I usually recommend rebuilding the carb after this happens to prevent a reoccurrence.

This sounds like a float problem. The carbs have a fuel chamber each and the amount of fuel in the chambers is controlled by a plastic float and needle valve. Carb will require stripping and cleaning and float adjusted. Not a job for DIY i'm afraid

first is there gas in the tank first, then check the fuel pump- take out the fuel hose that lead to the carburetor and crank the engine to see if fuel is coming, if not , check all hose leading to the tank - if ok , check the fuel pump- also check fuel filter too . let me know what is doing

sounds like the needle valve in the carbie leaking fuel past it,causing flooding

Hold the gas peddle to the floor when starting. The carb does not add fuel until the engine is running. Don't pump it as the accelerator pump will pump fuel each time you do it. Cause of problem is your float inside your carburetor is not seating correctly and "dribbles" fuel while your pump runs. Basically it is leaking inside and needs rebuilding..

hi how are you. remove the fuel line at the carbberator and crank engine and look for fuel comming out of line. if no replace fuel pump .if yes then your filter or carb needs to be replaced or repaired.
