Note. This section applies to vehicles equipped with an automatic choke control.
Open the hood and remove the air filter cover, which is secured with a wing nut and three clips.
Looking down on the carburetor in the middle of the air filter housing, you can see the flat carburetor choke located on top of the carburetor.
Ask an assistant to press the accelerator pedal, the carburetor choke should be completely closed. Start the engine and watch her.
Warning! Do not lean low over the carburetor - the engine may backfire, resulting in serious burns. When starting the engine, the choke should open slightly.
Start the engine and leave it to idle. As it warms up to operating temperature, the choke should open slowly, allowing more air into the carburetor.
After a few minutes of engine operation, the choke should open fully and move to the vertical position.
With the engine off, inspect the surfaces of the choke shaft for possible deposits that could cause the choke to jam. Use a special aerosol to clean the damper. Clean the damper shaft by turning the damper by hand.
Apply aerosol lubricant to the contact surfaces of the rod and check that the flapper moves freely.
