Apparatus (1) for use with a carburetor (C) to control the discharge volume from the carburetor's accelerator pump. A valve (5) controls flow of fuel from a fuel discharge port (O) of the pump. A vacuum operated means (9) moves the valve (5) from a position blocking fuel flow from the discharge port to a position permitting fuel flow. A switch (39) controls application of a vacuum to the vacuum operated means (9). A temperature sensor (57) senses engine coolant temperature and switches switch (39) when engine coolant reaches a predetermined temperature so the vacuum operated means (9) is exposed to atmosphere rather than engine vacuum.
