What is a hot air choke on a carburetor?

The hot air integral choke used a hot air source that was a tube that would be either pressed into the exhaust manifold or extended into a blind external chamber of the exhaust manifold. The integral hot air choke has proved to be by far the most functional and reliable of all automatic chokes.

What does a carb choke do?

A choke valve/cable is designed to restrict the flow of air in the carburettor of an engine. This helps enrich the fuel-air mixture, improving the ability to start an engine in low temperature conditions. Simply put, the choke is about making more fuel available for the engine to use.

Which way is choke on carb?

Choke is generally used in a naturally aspirated engine with carburetor. Choke is a butterfly valve that mounted on the inlet of air passage of carburetor (upstream from carburetor venturi tube).

What are the two types of carburetor?

The carburetor may have plain, double, vane, nozzle-bar and triple venturi. Each type of the venturi is designed to provide the decreased pressure of air flow so that it may draw fuel from the discharge jet. Multiple venturies help to keep the fuel away from the carburetor walls to reduce condensation.

Does choke open or closed carburetor?

The choke is a plate in the carburetor that opens and closes to allow more or less air into the engine. The choke is only used when starting a cold engine. When doing a cold start, the choke should be closed to limit the amount of air going in.

Should choke be open or closed when starting?

When doing a cold start, the choke should be closed to limit the amount of air going in. This increases the amount of fuel in the cylinder and helps to keep the engine running, while it is trying to warm up. If you are having trouble getting the car started in the morning, inspect the choke on your engine.

Is choke up or down?
