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.
What happens when you turn off the choke on an engine?
The choke increases the amount of fuel in the mixture, creating a richer mixture. This allows the engine to function at its best until it has warmed up enough to run on its normal operating fuel mixture. At that point the choke is turned off and the engine runs with a leaner fuel/air mixture.

Why does an engine only run on choke?
An internal combustion engine needs a precise mixture of fuel and air to run properly. When the engine is cold, it needs slightly more fuel in the fuel/air mixture for it to start, which is what the choke does. The choke increases the amount of fuel in the mixture, creating a richer mixture.
When to turn off choke control on outdoor power equipment?
We do not recommend that any type of outdoor power equipment be operated after initial warm-up and with the choke control outside of the normal run position for longer than 5 minutes. Some engines utilize a manual fuel primer bulb to enrich the ratio of fuel in the fuel air mixture for initial engine starting.
What causes a choke to stay on fast idle too long?
Stays on fast idle too long: The choke spring tension is too tight, the heat source is not being supplied or is blocked, or the fast-idle cam is gummed up, bent or has another problem that does not allow it to drop.
