Governor
The sail of the air vane governor is attached to the
throttle valve of the carburetor. Air flow created by
the rotating flywheel attempts to close the throttle.
The governor spring resists this force and attempts
to open the throttle. The balance between these
two
forces is the governed engine speed.
Governor Adjustment
To change the RPMs of the engine you change the
tension of the governor spring. Spring tension is
changed via an adjustable collar. When the collar is
turned each "click" produces approximately a 50
RPM change in engine speed.
SERVICING
The primer start carburetor used in V Engine has an
all Minlon housing with a fixed high speed jet and an
adjustable float.
Perform the following preliminary checks to
eliminate some of the other possibilities that may
contribute to hard starting:
Ignition system-
ensure that all components are
adjusted to specs and are the correct components.
Fuel tank fiiter-
must not be plugged.
