Best Carburetor Choke Thermostats of 2026
* We independently evaluate all recommended products and services. If you click on links we provide, we may receive compensation.
Carburetor choke thermostats are essential components of a carburetor system that regulate the engine's air-fuel mixture. They work by controlling the choke valve's opening and closing, which in turn affects the engine's air-fuel ratio. These thermostats are designed to ensure the engine starts smoothly in cold weather by enriching the fuel mixture with more fuel. As the engine warms up, the thermostat gradually reduces the amount of fuel in the mixture, resulting in a leaner fuel mixture. This helps improve fuel efficiency and reduces emissions. Carburetor choke thermostats are available in a variety of designs and configurations, and they are suitable for use in various types of engines.

Frequently Asked Questions (FAQs)
1. Should the choke be open or closed for cold start?
For a cold start, the choke should be closed. Pull the choke lever outward to close it, which provides the proper fuel-starting mixture when the engine is cold. As the engine warms up, slowly return the choke to the open position. When starting or restarting a warm engine, leave the choke in the OFF/OPEN position.
2. What controls the choke in a carburetor?
The choke in a carburetor can be controlled manually or automatically. A manual choke is operated by a lever on the side of the carburetor, which is connected to a lever or knob inside the vehicle through a cable. An automatic choke uses a metal spring to open and close the choke plate.
3. What happens if you leave the choke closed?
Leaving the choke closed when the engine is warm can result in a rich fuel mixture, meaning more fuel and less air. This can lead to increased fuel consumption as the engine burns more fuel than necessary for its operations.
4. What happens if you leave the choke open?
Leaving the choke open will not damage the engine. It will cause the engine to run richer, resulting in increased fuel usage. While running with the choke open for extended periods may lead to deposits in the engine/exhaust, it can be easily resolved.
5. How should an electric choke be wired?
To wire an electric choke, connect the bayonet end of the long electrical lead to the positive terminal on the choke cap. The other end should be connected to an ignition-activated 12-volt source. It is important to note that the distributor side of the ignition coil is not a 12-volt source but rather a 7-9-volt source after cranking.
6. What happens if choke stays closed?
If the choke stays closed or partially closed even when the engine is warm, it can result in a rich fuel mixture. This leads to increased fuel consumption as the engine burns more fuel than necessary for its operations.
