PROBLEM TO BE SOLVED: To solve the phenomena that inhibit such practical uses that, even when pressurizing fuel with high and stable pressure which can be obtained by setting a check valve in a passage communicating with a muffler and a fuel tank to exert high output in an engine for a model, performance in rising edge extremely worsen actually, moreover when the engine stops while the fuel remains, the fuel is pushed out into a carburetor so that the next starting becomes difficult. SOLUTION: The fuel is pressurized by installing a cock interlocking with a throttle valve set in parallel with the check valve in the passage communicating with the muffler and the fuel tank to obtain exhaust pressure on an idling and gradually increased pressure as a throttle opening enlarges.
