FUEL CAP

 WARNING

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.

REPLACING THE SPARK PLUG

RBC430SESD 

See 

fi

 gure 15.

RBC430SBD 

See 

fi

 gure 13.

This engine uses a Champion RY4C or NGK CMR7A 
spark plug with 0.6mm electrode gap. Use an exact 
replacement and replace annually.

 CAUTION

Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the engine.

CLEARANCE

See 

fi

 gure 14.

Inspect the camshaft-to-rocker arm clearance after every 
25 hours of operation or if the engine can't go idle or if the 
wide open throttle speed is too low. This should be done 
in a clean, dust-free environment.

NOTE: 

This procedure requires partial disassembly of the 

engine. If you are unsure if you are quali
