An electric choke can be found on a carburetor in an internal combustion engine. It has the important job of controlling the amount of air that is allowed to enter the engine. The electric choke helps the carburetor to perform this function. Unlike a manual choke, the electric choke does its job automatically. However, this does not mean that some troubleshooting on the choke might not be required from time to time.
Turn off your vehicle's engine. Do not attempt any electric choke troubleshooting while the engine is running. Wait for the engine and other internal components to cool.
Check the choke housing. There, you will find a lever. You should see the choke rod coming through the hole in the lever and secured with a fastener clip. If you don't, it has slipped out and will affect the electric choke's operation.
Look at the fast idle cam on the choke housing. This component should be above the choke rod, not below.
Verify that the screws that connect the choke cap gasket to the housing are secure and properly aligned.
Rotate the choke cap. If the bi-metal pick-up lever on the housing is fitted correctly, the choke plate should close with a counterclockwise turn and open with a clockwise turn. If you find that it's fitted wrong, refit the bi-metal pick-up lever into the bi-metal spring loop and make sure the ring on the choke cap is bowed outwardly, not inwardly.
