Float circuit float system
mechanism which maintains the level of fuel in the carburetor (32J.)
3.2.17
main metering system main circuit
high-speed system high-speed circuit
circuit in the carburetor (121) where fuel flows continuously during normal engine operation, except idling
3.2.18
slow speed system idle system
idle circuit
circuit in the carburetor (1LJ) where fuel flows at idling
3.2.19
secondary Idle system
secondary low speed system
circuit of the secondary carburetor (12.1) where fuel flows from the main fuel circuit when the opening of the throttle valve (1242) is small
3.2.20
power system
lull-power circuit
power enrichment system
circuit where additional fuel flows for the enrichment of air-fuel mixture at high power operation of the engine
3.2.21
starting system choke system
system or a series of parts in the carburetor (12.1) which restricts the air flow in the venturi (3.2.34) at the starting of the engine.ISO 7967-11-2014 pdf free download.
