           Coast enricher is located on the side of the carb. Both carb’s have one. On some of the older carbs the enricher is a separate piece. It is possible to disable this so you do not have to fool with it any more

The enricher can be disabled by removing the Diaphragm spring. This will seat the needle against the seat–retainer closing of the excess air to the pilot slot

           To the left is a break down of the parts in the order they are removed.

Actuator spring slides over the end of the needle which slides through the retainer. It contacts the diaphragm with the stiff diaphragm spring at the end
