Claims

[Scope of utility model registration request]

A starting fuel nozzle facing the starting intake passage and communicating with the float chamber is disposed in the middle of the starting intake passage provided in the carburetor body, and an inflow port connected to the upstream side of the starting intake passage. A sliding hole that opens an outlet connected to the downstream side on the inner surface is connected at an angle with the starting air intake passage, and a sliding throttle valve is slidably connected to the sliding hole, so that when the ambient temperature is high, In order to control the opening areas of the inlet and outlet from a fully closed state to a fully open state when the temperature is low, the sliding throttle valve is connected to a temperature-sensitive drive means that operates according to the ambient temperature. In the starting fuel adjustment device for a carburetor, the inlet and the outlet have an opening degree increase/decrease rate depending on the ambient temperature from a high temperature to around 25 to 39°C, and an opening degree depending on the temperature from around 25 to 39°C to a low temperature. A starting fuel adjustment device for a carburetor, characterized in that it is formed in a shape that is larger than the rate of increase/decrease.
