Here we have a 650 double pumper ( dual accelerator pumps) Holley carburetor with the float bowl level of fuel set too high on one side and too low on the other. Here I will demonstrate how you adjust and set your float level fuel height. You may want to do this if your classic car is running either too rich or too lean causing either flooding, hard starts and many other running problems. Car wont idle due to fuel mixture screws or in this case that both bowls were set at the wrong fuel height. If you are experiencing any kind of bogging or hesitation under acceleration, this may also be affecting you due to lack of fuel if fuel bowl level is too low. if you are experiencing flooding, your fuel may be set too high. if the level does not move up nor down no matter how much you adjust, your needle may be stuck in the seat. Try hitting the carburetor with the rubber/plastic side of a screwdriver and the impacts of the screwdriver can sometimes knock the needle loose.
