MAINTENANCE
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
Spark Plug
Level 2.
Parts Required:
Use only NGK BPM-8Y spark plug
(BPMR-8Y in Canada) otherwise
severe engine damage may occur.
1.
Remove spark plug and check for
fouling, worn and rounded center
electrode.
2.
Clean the plug or replace with a
new one. DO NOT sand blast to
clean. Remaining sand will damage
engine.
3.
Adjust spark plug gap by bending outer electrode.
4.
Tighten spark plug to 150-170 kgf • cm (130-150 in • lbf).
Cooling System
Level 2.
Parts Required:
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.
Overheating and engine seizure can occur when:
• Air intakes are blocked, preventing cooling air from reaching the cylinder.
