How can I tell if my car choke is bad?
What we usually see with a bad auto-choke is that the engine will start up and run great cold, but as the engine warms up there will be problems driving, starting, and/or idling. Remove choke assembly from the choke holder on the side of the carburetor. The needle should be clearly visible.
Why does my car stall when I close the choke plate?
Starts and stalls within a few seconds: If the choke plate closes properly and the engine starts and stalls almost immediately, the issue is usually not choke-related. This condition is likely the result of the carburetor float bowl losing fuel when the engine is turned off.
Can you adjust the choke while the engine is still warm?
Reinstall the air cleaner assembly over the top of the carburetor. Never adjust the automatic choke while the engine is still warm. Lubricate all linkages around the throttle lever to prevent the lever from sticking. Wear safety glasses when working around the carburetor.
What should I do if my choke does not work?
If the engine does not start when cranked over for a few seconds, release the key and press the accelerator to the floor one more time to evoke an additional accelerator pump shot. Most automatic chokes have a “clear flood” mode or “unloader” that is carburetor-linkage operated.

What happens to choke spring when engine is shut off?
As the engine warms up, the spring tension is reduced until the butterfly is completely open and has no impact on the signal the carburetor venturi (booster) is exposed to. When a hot engine is shut off and starts to cool, the tension on the choke spring increases in lockstep with the drop in temperature.
Is the choke on a scooter always active?
Further more, it is rarely possible that the piston does move, but not enough. Then you would need to know the positions for a working choke. If the choke works fine, disconnecting the cable will make it “always active”. The motor will start fine, but consume more gas and build up more soot.
