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 (Figure 15).
Operation in wet or damp weather or over freshly cut
grass may result in a variety of debris accumulating and
adhering to the internal shroud and fins of the cooling sys-
tem.

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 and replaced in the cylinder
head. Tighten the spark plug to the torque value specified
below (Figure 16).
