- Block the choke valve open - This lowers the outer tang on the fact idle operation lever so the secondary throttle pickup lever moves into position to open the valves.
- Slowly open the primary throttle valves the specified distance from the throttle bore walls. Approximately 3/4 open.
- The secondary throttle valves should just begin to open.
- To adjust the setting, bend the throttle link carefully at the angle. Support the link when bending so the connecting levers will not be distorted.
