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: Tune Up Kit.
Use only NGK CMR7H spark plug 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 102-153 kgf•cm (89-133 lbf•in).
Cooling System
Level 2.
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.
