Choke Inspection and Adjustment

Test conditions

Engine coolant temperature must be 80–95°C.
Headlights, electric radiator fan and all electrical loads must be switched off.

Transmission must be in neutral.
On vehicles with power steering, the front wheels must be set in the straight-ahead position.

PROCEDURE

1. Start the engine and let it run at idle speed.

2. Open the throttle valve fully until the free lever contacts SAS-3.
3. Close the throttle valve until SAS-2 contacts the free lever, and check the engine speed at this point.
4. If necessary, adjust the choke by turning screw SAS-3.
5. Disconnect the free lever, then check that the engine speed slowly returns to idle speed.
