After cleaning the engine, dry it well then inject a
small quantity of oil used to mix fuel and rotate the
crankshaft several times to distribute the oil well
inside the engine. Finally reassemble the engine
and store it in a dry place after inserting it in a heavy
vinyl bag.
When the engine is not to be used for a long period
(more than a year), remove the engine from the
model, clean the outside then remove the
carburetor, and plug all tubing. Clean inside the
engine by rotating the crankshaft with the engine
immersed in container filled with gasoline.
Also use gasoline to clean the outside of the
carburetor.
Clean the outside only because the inside parts are
sensitive to foreign substances.
