How does a carburetor choke work?
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.
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.

Why do I have to choke a warm engine?
The choke ‘chokes’ air going into the engine through the carburetor, effectively increasing the amount of fuel in the cylinder. In cold weather, this increases the chances of ignition. … In warm weather, a richer mix (more fuel in mix) is simply wastage of fuel as unburnt fuel is simply expelled.
Why does my chainsaw only runs on choke?
If your chainsaw only runs with the choke on, it is likely an issue with your carburetor. … If the carburetor is plugged, the engine will be starved of fuel and will not run. However, if the engine is plugged, the choke will pull more fuel through the carburetor’s idle circuit and allow it to run.

Why do generators only run on full choke?
Basically it can’t draw enough fuel with bad Diaphragm. If the engine only runs with the choke full on it means you have a vacuum leak and the engine runs too lean with the choke off. The only way to balance the fuel air mixture is to restrict the air by choking it. …
What happens if the choke is left on?
What happens if you leave the choke on too long? Leaving the choke on for too long will cause unnecessary engine wear and waste fuel. This is also bad for the environment. One a cold day, the engine can need more fuel than usual to get running – this makes the mixture ‘rich’, and this is what the choke does.
What’s wrong with my carburetor?
When a carburetor is clean and is working properly, the engine should start easily (hot or cold), idle smoothly, and accelerate without stumbling. … Problems that are often blamed on a “bad” or “dirty” carburetor include hard starting, hesitation, stalling, rough idle, flooding, idling too fast and poor fuel economy.
When should you choke your engine?
The choke allows for a richer fuel mixture to be sent to the engine, increasing the rpm’s on a cold engine. Without a choke, cold starts could cause very low idles on some cars, resulting in rough vibrations.
Should the choke be open or closed?
The choke is a plate in the carburetor that opens and closes to allow more or less air into the engine. … 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.
