THROTTLE LINKAGECheck
Ensure throttle return springs are correctly secured that throttle pulley moves freely, resting against closed stop when released (1).
Ensure that throttle butterfly closed stop screw has not been moved. If signs of tampering are present, check and if necessary, adjust (2).
Ensure that throttle pulley can be rotated to touch fully open stop and that throttle butterfly valve stop arm is touching throttle housing.
If conditions of above operations are not satisfied, proceed with operation 'Adjust'.
Adjust
If throttle butterfly closed stop has been moved, adjust the stop.
Check for worn pivots, damaged rods or linkage and trace of any stiffness.
Renew items as necessary.
Release throttle cross-rods from throttle pulley (3).
Slacken clamps securing levers to rear of throttle shafts (4).
With butterfly valve against closed stop, bellcrank against stop, and play in coupling taken up in opening direction, tighten clamp to lock lever to throttle shaft. Repeat for other side of engine.
Offer cross-rods to ball connectors on pulley; rods must locate without moving pulley or linkage. Slacken locknuts on cross-rods and adjust length of rods to locate pulley ball connector while bellcrank against closed stop (5).
Tighten locknuts and ensure ball joints remain free. Slacken locknut on throttle pulley, fully open stop and wind back adjustment screw.
Hold throttle pulley fully open and ensure that both throttle butterfly stop arms are against throttle housing.
Set fully open stop to just touch throttle pulley and tighten locknut.
Check operation of throttle switch.
