    FUEL SYSTEM FUEL VALVE When the engine is not operating, the fuel valve 1 is kept closed by the tension of the spring 2, which closes the fuel passageway and stops the flow of fuel to the carburetors. When the engine has started, negative pressure (vacuum) A is generated in the combustion chamber and reaches the diaphragm through a passage in the carburetor’s main bore and the vacuum hose.

    4-10 FUEL SYSTEM DIAPHRAGM AND PISTON OPERATION The carburetor is a variable-venturi type, whose venturi cross sectional area is increased or decreased automatically by the piston valve 1. The piston valve moves according to the negative pressure present on the downstream side of the venturi A. Negative pressure is admitted into the diaphragm chamber 2 through an orifice 3 provided in the piston valve 1.
  • Page 149: Slow System

    FUEL SYSTEM 4-11 SLOW SYSTEM This system supplies fuel during engine operation when the throttle valve 1 is closed or slightly opened. The fuel from the float chamber 2 is metered by the pilot jet 3 where it mixes with air coming in through the pilot air jet 4.
  • Page 150: Main System

    4-12 FUEL SYSTEM MAIN SYSTEM As the throttle valve 1 is opened, engine speed rises and negative pressure in the venturi A increases. This causes the piston valve 2 to move upward. The fuel in the float chamber 3 is metered by the main jet 4. The metered fuel enters the needle jet 5, mixes with the air admitted through the main air jet 6 and forms an emulsion.
  • Page 151: Starter (Enricher) System

    FUEL SYSTEM 4-13 STARTER (ENRICHER) SYSTEM Pulling the starter (enricher) plunger causes fuel to be drawn into the starter circuit from the float chamber 1. The starter jet 2 meters this fuel. The fuel then flows into the fuel pipe 3 and mixes with the air coming from the float chamber 1.
