ABSTRACT:
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.
