Claims

[Scope of utility model registration request]

A starting fuel nozzle that communicates with the float chamber is disposed facing the middle of the starting intake passage provided in the carburetor body, and a sliding throttle valve that holds a metering needle valve inserted into the fuel nozzle is arranged as described above. In a starting fuel adjustment device for a carburetor, the carburetor main body includes a starting fuel adjustment device that is slidably disposed in a direction forming an angle with the starting intake passage in order to control the opening area of the starting intake passage. A series of angled holes are drilled in the middle of the air intake passage, into which a sleeve that is basically cylindrical with a bottom and has the starting fuel nozzle fixed to its closed end is fitted and fixed. and the sleeve includes:
An inflow hole communicating with the upstream side of the sleeve of the starting intake passage and an outflow hole communicating with the downstream side of the starting intake passage are bored in a straight line, and the sliding throttle valve has the following features:
1. A starting fuel regulating device for a carburetor, characterized in that the device is slidably fitted onto a sleeve to open and close between an inflow hole and an outflow hole.
