LUBRICATION

All rotating and sliding parts are splash lubricated by the oil
scraper on the connecting rod.

IGNITION SYSTEM

The ignition system is a transistor controlled magneto ignition
system which consists of a flywheel and an ignition coil with a
built in transistor. This system has an ignition timing advance for
easy starting. Ignition timing is fixed by location of parts. No
adjustment is required.

DECOMPRESSION SYSTEM

An automatic decompression mechanism which opens the
exhaust valve before the piston reaches compression top is
assembled on the camshaft for easy starting.

CARBURETOR

The carburetor has a float controlled fuel system. The carburetor
is calibrated carefully for good cold weather starting, good
acceleration, low fuel consumption, and sufficient output.
