Install the air vane and throttle shaft into the
carburetor body by very carefully pushing the shaft
through the collar into the carburetor body. (See
Figure 37.)
A
Push the throttle plate into the throttle shaft. (The
plate only inserts one way.) If the throttle plate
does not fit snugly, replace the throttle shaft. The
governor spring can now be attached to the throttle
shaft.
Note: Be sure air vane operates smoothly and
does not stick or bind.

heat shield, and air filter box. Use the two
mounting screws to hold the parts together during
assembly.
Check that the choke and air vane assembly move
freely and is properly adjusted. If the air vane
requires adjusting, see Presetting the Governor on
page 26.
R tek - Assemble the carburetor, spit cup, heat
shield, and gaskets. Use the mounting screws to
hold parts together during assembly.

DuraForce engines - Guide the air vane through
the opening in the shroud base from the bottom of
the base, and attach the carburetor to the engine
with two mounting screws. Tighten them to
specifications.
Governor Theory
DuraForce engines - Insert the bent wire of the
throttle cable into the vertical tab of the speed
control lever. Set the throttle to fast and the speed
control lever so that the throttle plate is in the full
open position. The cable is adjusted at the cable
clamp on top of the air filter box.
Reed Valve Engine
(DuraForce Engines Only)
The shaft of the governor air vane is attached to the
throttle disc of the carburetor so that 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. Spring tension
may be changed via an adjustable collar which
R tek engines - Connect the governor spring to the
throttle plate and the tab on the block. Connect the
governor rod adjusting loop (A) up to the air vane,
and connect the choke cable. Assure the throttle is
in the full open position. (See Figure 38 and Figure
40.)
produces a 50 - 75 RPM change in engine speed for
each adjustment “click” it is moved. (See Figure 39.)
