Why does my 2 stroke engine only run on choke?
When you turn the choke on for a carburetor, it is creating a rich condition.
So, when your bike only runs on choke, it is because the “rich” mixture that is being burned is actually closer to the appropriate mixture.
Then, when you turn the choke off, it becomes much too lean and will not run..
Which position is choke on?
A rich mixture is needed to start your bike when it is cold… colder than a cup of coffee. Typically the “choke” is on when the choke lever is in the up position or when the choke lever is inline with the handle bars on your bike. Choke on means that the choke plate is covering the carb throat.
How long should I leave the choke on?
30 secondsThe choke usually “chokes” the air supply into the engine so it gets more petrol than usual. Hence it’s name. You should start the bike from cold with half or full choke depending on how cold it is. After 30 seconds is usually enough for most bikes.
What would be the effects of a sticking automatic choke?
If the choke valve sticks, the mixture will stay rich. Your warmed-up car will be hard to start, run poorly and waste precious gasoline. A bi-metallic spring in the choke housing on the carburetor is connected to the shaft that the flap rotates on.
How do I change my automatic choke to manual?
Fitting a choke conversion kitDisconnect choke. If the choke is plumbed into the cooling system, take off the radiator cap and disconnect the two hoses from the choke. … Remove choke unit. … Fit interface. … Fit adapter. … Cable anchor plate. … Cable spool. … Dash mounting. … Wiring up.More items…
How do you tell if the choke is open or closed?
When the choke butterfly is allowing the most air flow, without restriction, it is open. Like a door. Open lets things through. when the choke is restricting the flow of air, it is closed.
What does the choke do on a quad?
An ATV choke works by blocking some of the air from entering the carburetor and mixing with the fuel. When the choke is on, the air/fuel mixture entering the engine is a lot richer (more fuel than normal) which helps start and keep an engine running if it’s cold.
How do you fix an automatic choke?
Watch the butterfly valves inside the carburetor while turning the automatic choke element clockwise until the butterfly valves are standing straight up. Turn the choke element counterclockwise until the butterfly valves are fully closed. Tighten the three automatic choke element screws with the screwdriver.
Should the choke be closed when running?
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.
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.
