how to use a choke to start an engine

How do you know if choke is open or closed?

Turn on the ignition of your car. Once the engine is warm, you can remove the air filter and check whether the choke is open or closed. At this point, the choke should be open to allow the engine to breathe fully.Jul 5, 2016

Is the choke on or off?

When the choke lever is pushed up, the choke is on and when it is pulled down, it goes off. You could also pull the lever halfway down during operation or halfway up at the beginning of the operation. The colder the engine, the more fuel it needs, and thus, the higher the lever should go.

Do you leave the choke on or off?

Leaving the choke on for too long will cause unnecessary engine wear and waste fuel. This is also bad for the environment. The choke is mainly used during winter to help with starting. The engine needs its fuel to be vaporised in order to burn it.

How does a choke help start an engine?

A cold engine won't vaporise the fuel as well as it would in warmer conditions, so the choke helps enrich the mixture (either by adding in more fuel or cutting out airflow) to increase the amount of combustible vapour available to start the engine.Aug 27, 2019

How does the choke start a cold engine?

The instruction manual for Yugo says that when you want to start a cold engine you must pull the choke and do not press the gas pedal.

When should you use engine choke?

In internal combustion engines with carburetors, a choke valve or choke modifies the air pressure in the intake manifold, thereby altering the air–fuel ratio entering the engine. Choke valves are generally used in naturally aspirated engines to supply a richer fuel mixture when starting the engine.
