N722W

The experimental homebuilt airplane was in cruise flight at 7,500 feet when the engine lost power. The pilot navigated toward the nearest airport by GPS, which was 16 miles away. The pilot found he could restore partial power by continuously pumping the primer handle. Upon reaching the airport, the engine stopped producing power when the pilot reached for the flap handle. The airplane was "high and fast" and touched down at the midpoint of the 3,000-foot runway, then overran the departure end. Examination of the engine, ignition and the fuel system revealed no mechanical deficiencies. Disassembly of the carburetor by an FAA inspector revealed a stuck float needle in its seat, that was freed during disassembly. No other discrepancies with the carburetor were found.
