Checking the Fuel Cap
WARNING:
A leaking fuel cap is a re hazard and must be
replaced immediately.
The fuel cap contains a non-serviceable lter and check
valve. A clogged fuel lter causes poor engine performance.
If performance improves when the fuel cap is loosened,
the check valve may be faulty or the lter may be clogged.
Replace the fuel cap if necessary.
