Dashpot Adjustment
- Bring engine to normal operating temperature. On Turbo models, disconnect and plug EGR hose. On all other models, disconnect and plug vacuum advance. Connect tachometer and check idle speed. Adjust if necessary.
- Rotate throttle lever and check that dashpot rod strikes the stop at 2100-2300 RPM on Turbo models, or 2400-2600 RPM on all others. If not, adjust by turning dashpot.
- Accelerate engine to 3000 RPM and measure time from release of throttle until engine reaches idle speed. Deceleration time should be 3-6 seconds. If not, turn dashpot in toward stop to lengthen delay, or away from stop to shorten delay time.
