I have been having problems with my 91A - 99 carb flooding. I checked the fuel pressure from the pump and got 4# of pressure which is too much, so I cut a coil from the fuel pump spring and now have 3 1/4 # of pressure. The carb still floods at idle. I had the carb off and apart and cleaned every passageway and blew them out. I did remove a strange piece of debris in the needle valve area. The needle valve is of the blunt end variety and not the pointed type. The end toward the seat has some type of material on it to aid in getting a good seal.. I am leaning toward replaceing the needle and seat with the pointed type valve. Is 3 1/4 # too much? The float is set at 1.355.

Would appreciate any advice on this problem.
