Now this is coming out of the user Manual that covers the GQ series (Doesnt say what year ranges though)
The knob you are refering to Scott is the "Idling control knob"
It is used when starting the vehicle or alternativley "The engine can be maintained at the desired speed without depressing the accelerator pedal. Example - When using mechanical type winch. Avoid driving the vehicle with the throttle/idling control knob pulled out"
Starting the RD28:
Normal starting conditions:
1. Apply the parking brake
2. Move the gearshift leaver to "N" and depress the clutch pedal to the floor while cranking the engine.
Cold starting
1. Turn the idling control knob fully clockwise.
2. Turn the ignition key to "ON" and wait for the glow indicator light to go out.
3. Immediately after the glow indicator light goes out, fully depress the accelerator pedal and crank the engine by turning the ignition key to "START". Release the key and the accelerator pedal when the engine starts.
4. Adjust the idling control knob until the engine runs smoothly.
5. After the engine warms up, return the idling control knob to its original position.
* Proper use of the idling control knob will reduce startup smoke.
* Do not drive the vehicle with the idling control knob pulled out.
So there you go. Directly from the User Manual from the manufacturer.
