FUEL SETTING ADJUSTMENT (Contd)

NOTE

Ensure clamping screw is not protruding from threaded hole on hook

end of control linkage positioning tool. Any protrusion will result in

improper installation of control linkage positioning tool.

Turn clamping screw on control linkage positioning tool until end of clamping screw is inside of

threaded hole.

Turn limit screw on control linkage positioning tool until nylon spacer is seated against control

linkage positioning tool.

Position control linkage positioning tool on control linkage shaft (2) between No. 4 (1) and No. 5 (3)

rocker arm supports.

CAUTION

Once installed, the control linkage positioning tool must not be

removed, loosened, or allowed to slip on the control linkage shaft. If the

control linkage positioning tool does not stay clamped in this position

until after double zero is set, the control linkage positioning tool must

be tightened again before double zero can be set.

NOTE

Ensure limit screw seats against cylinder head while tightening

clamping screw.

Install control linkage positioning tool on control linkage shaft (2) by pressing down on limit screw

while tightening clamping screw until it grips control linkage shaft (2) securely.

NOTE

Rotating the control linkage shaft toward the push rod side of engine

will move all rack bars toward the "fuel-off" position and help free any

rack bars which may be hanging up or binding.

Ensure control linkage positioning tool moves freely and does not touch

rocker arm supports.

Ensure limit screw seats against cylinder head when control linkage

positioning tool is released.

10.

Move control linkage positioning tool toward push rod side of engine to rotate control linkage

shaft (2), then release.

NOTE

When the fuel shutoff solenoid is removed, the rack bars move into the

"fuel-on" position. This is necessary to set and check the fuel setting.

11.

Remove fuel shutoff solenoid (WP 0050 00).

12.

Move control linkage positioning tool toward push rod side of engine and hold.

NOTE

Assistant will help with step 13.

13.

Set double zero on the horizontal dial indicator.

a. Loosen red thumb screw on side of holding fixture and slide horizontal dial indicator laterally

until small needle lines up on zero. Tighten red thumb screw.

b. Loosen bezel screw on horizontal dial indicator and turn bezel until large needle lines up on

zero. Tighten bezel screw.

14.

Release control linkage positioning tool.

15.

Pull and release control linkage positioning tool several times to ensure horizontal dial indicator

reads double zero on the push rod side of engine.

a. If horizontal dial indicator does read double zero, go to step 16.

b. If horizontal dial indicator does not read double zero, repeat steps 12 through 15.
