NOBODY MAKES A SPARK PLUG FRONT 100,000 ENGINES. NOBODY. THEY ARE BY HEAT RANGE AND SIZE.
THAT MEANS SET THE GAP TO OEM TOY SPEC.
NGK CATALOG ONLINE EVEN TELLS THAT SPEC.

IDLES HIGH COLD OR HOT ENGINE OR BOTH
NOT TOLD AND IS A KEY FACT NOT TOLD.
THE SPEC IS
IN THE SM

Adjust the spark plug electrode gap. Electrode gap for new spark plug is 1.0 to 1.1 mm (0.039 to 0.043 in.).
BEST IS 1MM SET, AND THAT LOWER SETTING
ALLOWS THE GAP TO WIDEN IT IT AGES AND RUN LONGER AND BETTER.

NO PLUGS TOLD
THE OEM TYPE CALLED J PLUGS ARE SET PER ABOVE
BUT SOME ODD DUCK BOSCH SURFACE FIRE

The spark plug gap will already be set when manufactured! You will need to give the engine type, size and year for anyone to give you the information.

same as factory plugs call parts store they can tell u the exact gap

  • Loose spark plug
  
  
  
  • Plug heat range too hot
  
  
  
  • Insufficient cooling
  
  
  
  

• Fouled plug may be caused by:
  
  
  
  
  
  
  • Retarded ignition timing
  
  
  
  • Oil in combustion chamber
  
  
  
  • Incorrect spark plug gap
