COOLING SYSTEM CLEANING
At least once a year, or more often under adverse condi-
tions, the cooling system should be cleaned. Cleaning will
assure an adequate supply of air to the cooling fins. Com-
pressed air may be used for routine cooling system main-
tenance.
Operation in wet or damp weather or overly fresh cut
grass may result in a variety of debris accumulating and
adhering to the internal shroud and fins of the cooling
system.

This engine uses Spark Plug NGK BPR2ES with a gap of
.028" - .031" (.70 - .80 mm). Using a 13/16" spark plug
socket or wrench, remove the spark plug at 125 hours or
semi-annually and clean and re-gap. The spark plug
should be properly gapped (Ref. Fig. 15) and replaced in
the cylinder head, tighten to the specified torque.
Fig. 15 Gapping the Spark Plug
Fouled spark plugs are indicated by a wet, black appear-
ance. This could be caused by a dirty air filter element or
other restrictions in the air intake system. Incorrectly
adjusted valves, spark plug wires which are in poor condi-
tion or poor quality fuel could also contribute to the prob-
lem.
Use care not to over-tighten the
plug. Over-tightening can cause
damage to the aluminum cylinder
head threads.
