mately two months or more, use the following
storage procedure.

hole with thumb and turn engine over until the
piston is at the top of its stroke (pressure
against thumb is greatest). Reinstall plug, but
do not connect plug lead.
6. Clean the exterior surfaces of engine. Spread
a light film of oil over any exposed metal sur-
faces of engine to prevent rust.
