Procedure

1. 11. Assemble new rubber dust seal (7) against throttle shaft bearing, with lips of seal toward the outside.
2. 12. Install and stake the seal retainer washer (8).
3. 13. Assemble throttle shaft and lever (9) with wide open stop lug (narrow lug) on shaft lever in contact with stop on casting when shaft is in the wide open throttle position.
4. 14. Hold bowl cover inverted with mounting flange toward the operator's right.
5. 15. Install throttle plate (19) with mark stamped on throttle plate on high side of plate and toward the operator.
6. 16. Start, but do not tighten both throttle plate screw and lockwasher (11).
7. 17. Gently tap high side of throttle plate to center the plate. Hold in this position with left index finger and tighten throttle plate screws.
8. 18. Install throttle stop screw (5) and spring (6).
9. 19. Install the idle adjusting needle (3) and spring (4).
10. 20. Install the fuel valve seat (15) with fibre washer (14). Use tool C161-85.
11. 21. Assemble fuel valve needle and bowl cover gasket (16).
12. 22. Carefully examine the float assembly (12) for evidence of wear or damage. This type of float is not adjustable and wear in any part of the fuel valve and float hinge assembly will raise the fuel level.
13. 23. Install the float and float axle pin (13). Insert the bowl cover and check the float in the closed position. The float setting will be within limits if the float is parallel to the gasket seating surfaces of the bowl cover. Any necessary float correction should be made by replacing worn parts. DO NOT attempt to bend the float bracket.
14. 24. Attach bowl cover assembly (1) to bowl by means of the three assembly screws (2).
