Choke Cable and Housing Installation
In the following text, there are references to removing/install-
ing bolts etc. Additional hardware (nuts, washers etc.) that are
removed must always be installed in their original positions
unless otherwise specified. Non-specified torque specifica-
tions are as shown in the table contained in Section ‘A’.
Feed the choke cable assembly (8) through the hole in
the bezel (7) (Ref. Fig. 3 on Page H-2). Insert the cable
and bezel into the seat panel and install the bezel
retaining bracket (6), lock washer (5) and nut (4) finger
tight. Slide the threaded portion of the housing through
the carburetor mounted bracket and attach the nuts (2)
to the choke cable housing finger tight. Pass the choke
cable through the choke arm swivel and tighten the
swivel screw (9) after being sure that the choke and
choke knob are both in the open position.
Adjust the position of the curved portion of the cable
housing to ensure that the cable does not contact the
belts or other moving parts. Check the cable to be sure
that there are no sharp bends or kinks in the cable
before firmly tightening the nuts at both ends of the
cable.
Carburetor Service
Be sure that the ignition system is functioning correctly
before determining that servicing the carburetor is
required. Refer to ELECTRICAL section for ignition sys-
tem information.
To prevent an ignition spark which could ignite
gasoline from the fuel system and result in
personal injury, the negative battery cable
must be removed from battery (see Section
‘B’).
