Page 145: Slow System
FUEL AND LUBRICATION SYSTEM 5-11 SLOW SYSTEM This system supplies fuel to the engine during engine operation with throttle valve 1 closed or slight opened. The fuel from the float chamber 2 is first passage and metered by the pilot jet 3 where it mixes with air coming in through #1 pilot air jet 4 and #2 pilot air jet 5.
-
Page 146: Main System
5-12 FUEL AND LUBRICATION 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 moves upward. The fuel in the float chamber 3 is metered by the main jet 4. The metered fuel passes around main air bleed pipe 5, mixes with the air admitted through main air jet 6 to from an emulsion and emulsion fuel enters needle jet 7.
