Do you start with choke on or off?
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. … Once the car has warmed up, if the choke does not open fully, the restriction in air may result in reduced power.
How do you use a choke?
How to Use a Manual Choke on a Car
- Pull the manual choke knob to decrease the air intake and provide a richer fuel-to-air ratio before you start the ignition. …
- Pull out the choke knob more for a cold engine start, or on a cold day. …
- Switch on the ignition and start the engine.
What happens if 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.
Is it bad to run an engine with the choke on?
Leaving the choke on while operating will result in excessive fuel consumption, irregular engine power performance and eventually may even damage the engine. … Some engines utilize a manual fuel primer bulb to enrich the ratio of fuel in the fuel air mixture for initial engine starting.
How long should you choke a motorcycle?
After 30 seconds is usually enough for most bikes. Especially a small thumper. Just reduce the choke slowly. If it wont idle smoothly (sounds like an asthmatic pensioner) then it probably wants the choke on a bit longer.

Make sure both tires are in good condition before starting a ride. Ensuring there are no embedded objects and bulges, and monitoring the wear of your tires may contribute to a safer ride. It’s also a good idea to check your tire pressure, especially when it’s cold outside, to make sure they have enough air.
Is choke up or down motorcycle?

How the choke works on a carburetor?
By restricting the flow of air into the throat of the carburetor, the choke valve reduces the pressure inside the throat, which causes a proportionally greater amount of fuel to be pushed from the main jet into the combustion chamber during cold-running operation.
Do fuel injected bikes have chokes?
It’s not a choke. It’s really a fast idle thingy (technical term) to bump up the idle speed while the engine is warming up if the fuel injection can’t cope properly when it’s idling and cold.
