    摘要： The object of the present invention is to provide an internal combustion engine for solving the problem of fuel leakage through an air vent of an carburetor.An internal combustion engine comprises a fuel tank; a carburetor having an air vent at a location above the fuel tank; a fuel circulation passage for supplying fuel from the fuel tank to the carburetor on a upstream side thereof and returns oversupplied fuel to the fuel tank on a downstream side thereof; and a fuel capturing chamber communicated with the air vent, the fuel capturing chamber having an air bleeder so that the fuel which flows backward from the fuel tank through the downstream side of the fuel circulation passage and leaks through the air vent is captured in the fuel capturing chamber.

    摘要： A carburetor includes a main fuel path connected to a main nozzle and a slow fuel path connected to a slow port. The main fuel path and the slow fuel path are separated from each other and are independently communicated to a constant fuel chamber below a fuel level of the fuel chamber. The slow fuel path includes a first slow jet located above the fuel level and a second slow jet located in the downstream of the first slow jet. A opening size of the second slow jet is smaller than that of the first slow jet, and the first and second slow jets are arranged in series.
