  1. If removed, install check valve in fuel inlet filter. The fuel inlet check valve must be installed in the filter to meet Motor Vehicle Safety Standards (MVSS) for roll-over. New service replacement filters must include the check valve.

  2. Install fuel inlet filter spring, filter, and check valve assembly in carburetor. Check that the valve end of filter faces toward the fuel line. Ribs on closed end of filter element prevent filter from being installed incorrectly unless forced.

  3. Install nut in carburetor. Tighten nut to 18 ft. lbs. (24 Nm).

  4. Install fuel line and tighten connection.

  5. Start engine and check for leaks
