Choke
Assembly
(Prior
to
Spec D Gasoline and Spec F LPG*)
Choke Settings: Table 6-2 lists choke settings for
various ambient temperatures. Stop the set and let
it cool before adjusting the choke.
1.
Remove the plastic choke cover (see Figure
6-22) and loosen the heating element cover
screws.
2. Rotate the heating element until the choke
plate is halfway open.
3.
Slowly rotate the cover counter clockwise while
tapping the carburetor choke lever to make it
bounce. Continue until the lever no longer
bounces. This is the fully-closed (reference)
position.
4.
Refer to Table 6-2 to determine the number of
degrees the element cover must be rotated
clockwise from the reference position. The
marks on the choke housing are spaced at 5°
intervals.
5.
Rotate the element cover as specified, then
tighten the cover mounting screws.

6. Move the choke lever to test its operation. The
lever should return to the free position when re-
leased from the open position, without sticking
or binding.
7. Install the plastic choke cover and tighten the
center mounting unit.
