Note: Federal EPA regulations require all model year 2012 and later
gasoline powered engines produced for sale in the United States
to be equipped with a special low permeation fuel supply hose
between the carburetor and fuel tank. When servicing model
year 2012 and later equipment, only fuel supply hoses certified
by EPA can be used to replace the original equipment supply
hose. Fines up to $37,500 may be enforced for using an un-
certified replacement part.

for fouling, worn and rounded
center electrode.

a new one. DO NOT sand

To maintain proper engine operating temperatures, cooling air must pass
freely through the cylinder fin area. This flow of air carries combustion
heat away from the engine.
