TO say that the best advice that
can give you with reference to the

The adjusting screws OF the carbu-
rotor are always locked. so that they
cannot Of themselves move. There

Unfortunately. the person who knows
little about this engine WIZ when
something goes wrong. Immediately

as he cannot get u shock from 1t. and
those screws are handy. 1t is cx-

Water in the gasoline may cause
the engine to stop suddenly. but
usually the stopping is accompanied
by popping" in the carouretor and
a loss of power. Sometimes the water
