摘要： PROBLEM TO BE SOLVED: To provide a carburetor whose low speed system is independent from a main system, wherein connection of fuel is smooth, dispersion in fuel flow rate is low, and high output is materialized.
SOLUTION: A flow rate control mechanism 21 is provided to a low speed system 12 independent from a main system 8. In the mechanism 21, a valve element 24 is linearly reciprocated with a cam 32 provided to a throttle valve shaft 6. The effective area of a low speed fuel passage 16 is increased to main fuel injection timing in accordance with increase in opening from an idle position of the throttle valve. After that, the area is decreased to be made zero at high output area. By so doing, the fuel flow rate in a high pressure area is stabilized and high output is materialized while the connection from low speed fuel to main fuel is made smooth.
