Liner O-Rings and Packing

NOTE: Piston and liner sets differ between engines. DO
NOT mix piston and liner sets. See parts catalog
for correct applications.
IMPORTANT: DO NOT use oil on cylinder liner
packing or O-rings. Oil can cause the
red packing to swell, which squeezes
liner and could possibly cause a scored
piston.

to soak.
