Coasting Richer System: Operation: Notes

When accelerator switch, clutch switch and transmission switch are "on", coasting solenoid valve on secondary side of carburetor is energized. This opens fuel passage from coasting jet and air bleed which supplies additional fuel into lower part of secondary throttle. Fuel mixture is now enriched temporarily for efficient combustion during coasting.
