GENERAL INFORMATION

Inspection: Push the damper rod down into the throttle damper and check that the rod descends slowly. Then release the rod and check that it returns quickly to its original position. If not, replace the throttle damper.

Replacement

PROCEDURE

1. On models with a carburetor engine, remove the two mounting screws and remove the throttle damper from the side of the carburetor.

2. On models with electronic fuel injection, remove the mounting nut and remove the throttle damper from the throttle body mounting bracket.

3. Installation is the reverse of removal. After installation, start the engine and warm it up to normal operating temperature. With the engine idling, have an assistant slowly depress the accelerator pedal and observe the throttle damper. Note the engine speed at which the adjusting screw contacts the end of the damper rod. This should occur at 2500±200 rpm. If adjustment is necessary, loosen the locknut and turn the adjusting screw as required. Recheck the speed at which the adjusting screw contacts the damper rod, and tighten the locknut once the screw is correctly adjusted.
