water and salt from the electrical com-
ponents.
3. Drain all fuel from the fuel hoses, fuel
pump, fuel filter (See page 67) and

Keep in mind that if gasoline is kept in
the vapor separator for a long time,
gum and varnish will develop, causing
the float valve to stick, restricting the
fuel flow.

spoon of engine oil or spray storage oil
into the combustion chamber through
the spark plug holes.
5. Turn the starter motor several turns to
lubricate inside the cylinder.
