Engine Cylinder
Remove the spark plug
(page 38). Pour a tablespoon
(5 ~ 10 cc) of clean engine oil
into the cylinder. Pull the starter
rope several times to distribute
the oil in the cylinder. Reinstall
the spark plug.
Pull the starter rope slowly until
resistance is felt then return the
starter grip gently. This will
close the valves so moisture
can not enter the engine
cylinder.
