Carbureted Models Only

A constant velocity (C.V.) carburetor uses an enrichener instead of a choke. An enrichener is operated almost the same way as a choke except there are two differences:

When starting a cold engine, the throttle control MUST BE CLOSED for the enrichener to work properly.
The enrichener does not have detents. The enrichener knob position can be adjusted from full-in to full-out.

See Figure 1. Engine speed increases as the enrichener knob is pulled out. By moving the enrichener knob, you adjust the air/fuel mixture to start a cold or warm engine.

1.	Pull enrichener knob all the way out for cold engine starting.
	NOTICE Pay close attention to the vehicle's warm-up time. Either excessive or insufficient use of the enrichener may cause poor performance, erratic idle, poor fuel economy, spark plug fouling and equipment damage. (00164a)
2.	Change the enrichener knob position between full-out or full-in as the situation requires.

NOTE

See OPERATION section for detailed starting procedures.

Only carbureted models use an enrichener.

1	Enrichener knob
2	Full-out (cold engine starts)
3	1/2 way position
4	Full-in (normal running position)
