4-9 GOVERNOR SYSTEM
The governor is a centrifugal flyweight type which
ensures constant operation at the selected speed
against load variations.
The governor gear with governor weights is installed
on the main bearing cover.
4-10 COOLING SYSTEM
The engine uses a forced air-cooling system in which a
synthetic resin cooling fan (which is separate from the
flywheel), reduce noise and forces cooling air into the
cylinder and cylinder head.
Baffles are provided to guide the flow of cooling air.
4-11 LUBRICATION SYSTEM
The rotating parts, sliding parts and valves of the engine
are lubricated with oil in the crankcase.
Lubrication oil is splashed onto those parts in the case by the
oil splasher on the connecting rod.
4-12 IGNITION SYSTEM
The ignition system is a transistor controlled magneto
system which consists of a flywheel and an
ignition coil with a built-in transistor mounted on
the crankcase.
This ignition system has latest automatic ignition timing
control for easy start.
4-13 CARBURETOR
The engine is equipped with a horizontal draft
carburetor.
The carburetor setting is calibrated after
careful testing for optimum all-round performance
(including starting, acceleration, fuel consumption,
output power characteristics).
Special attention is
also paid to the general-purpose use of the engine.
