Sorry to give a different slant to this topic but I have an SU carb on a high compression headed in a 19 29 fabric bodied saloonwhich floods badly to the point of causing the engine to stop. Once it sits for a while it starts again but floods to a stop again. There is no spring or damper in the carb - just a simple brass screw in cap with a screwdriver slot (not knurled). Question is should there be a spring or a damper. It has an electric fuel pump but the float in the bowl works fine as after a couple of clicks the pump stops prior to starting. Any answers as to spring and damper much appreciated.
