FUEL CAP
A leaking fuel cap is a fi re hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable fi lter and a
check valve. A clogged fuel fi lter will cause poor engine
performance. If performance improves when the fuel cap
is loosened, check valve may be faulty or fi lter clogged.
Replace fuel cap if required.

RBC430SESD
See fi gure 15.
RBC430SBD

This engine uses a Champion RY4C or NGK CMR7A
spark plug with 0.6mm electrode gap. Use an exact
replacement and replace annually.
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the engine.
