Fast Idle Opening Angle Adjustment
- Close choke valve to fully closed position. Align fast idle adjusting screw on the first (high) step of fast idle cam. See Fig 1.
- Measure clearance between primary throttle valve and throttle valve chamber wall. Clearance should be.048-.058" (1.23-1.47 mm). Primary throttle valve angle should be 25 degrees. If clearance is not as specified, adjust using fast idle adjusting screw.
