Why Do I Have To Choke A Warm Engine?

What is engine choke control?

A choke control is a fuel and air mixture control system found on many carbureted engines.

When an engine carburetor is “choked”, the fuel to air mixture ratio becomes richer (more fuel & less air) than normal, for easier cold starting and to assist in getting the fuel flowing through the system..

What happens if the choke is left on?

Leaving the choke on for too long will cause unnecessary engine wear and waste fuel. … The engine needs its fuel to be vaporised in order to burn it. This is done by the carburettor where the fuel is mixed with clean air coming from the air filter, and sent into the pistons to be ignited.

Why does my motorcycle take so long to warm up?

Also, the motorcycle engine being air-cooled probably means it takes longer to come up to operating temperature. It’s in full cooling mode, so to speak, all the time. A water-cooled engine keeps the cooling system turned off until the engine is warm, so it can warm up faster.

What happens when you choke a motor?

When the choke is cranked to the highest level, it attracts the fuel through the idle port and combined with reduced air supply, creates the solution need to start a cold engine. … When this does happen, the spring inside the carburetor doesn’t heat up as quickly as it’s supposed to causing the choke to open slowly.

Is it bad to run an engine with the choke on?

What is the purpose of a choke on an engine?

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.

How do you tell if choke is on or off?

When should you choke your engine?
