How do you open the choke on a lawn mower?

Last Updated: 10th May, 2021

A typical starting procedure for an engine with a choke might be:
  1. Close the choke (usually on carburetor).
  2. Set the throttle control (if any) to the START or HIGH position.
  3. Pull the starter cord once or twice (if it doesn't start on the first one).
  4. If it still doesn't start, open the choke half way.

Accordingly, where is the choke on a riding lawn mower?

Pull the throttle into the choke position. It may be next to the seat on the left side. Many throttles are identifiable because they indicate speed by a picture of a rabbit and turtle. Move the throttle lever so it engages the choke.

Beside above, why do I have to run my mower with the choke on? Lawn Mower: Only Runs With The Choke On. If your lawnmower will start and run with the choke on but dies when the choke is turned off, it may have a problem with the carburetor. The carburetor brings air and fuel together and mixes them in the perfect ratio for combustion before they enter the engine.

Subsequently, question is, how do I know if my 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 happens if you run an engine with the choke on?

3 Answers. It will not damage the engine at all. All that will happen is that it will run richer, thus using more fuel. If you did it for thousands of miles you'd probably end up with more deposits in the engine/exhaust, but even that is easy to sort.

Can you bump start a ride on mower?

Some riding mowers can be push-started like a car with a manual transmission. I'll tell you how to do it, but keep in mind that this will only work on riding mowers that have a clutch. If you don't have a long, fairly steep hill on your property, you'll need a friend to push.

Where is the choke on a John Deere lawn mower?

Locate the screw just behind the throttle control linkage. Turn the screw clockwise until the end of the screw is just touching the choke control lever, which you can see by looking through the hole in the carburetor control plate, directly to the left of the throttle cable.

Which way is choke?

The choke is located before the throttle, and manages the total amount of air going into the engine. 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.

How long should I leave the choke on?

The 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.

Does choke Richen or lean?

Basically, the choke works by limiting the amount of air that mixes with the fuel. More fuel and less air makes for a rich mixture. As I'm sure you know, you cannot have combustion without oxygen. BTW, a lean mixture is the exact opposite, more air and less fuel.

Should Choke be up or down?

If you have the NT carburetor the choke is on (closed) when the lever is up. If the engine isn't running it doesn't make any difference where it is. The choke should be off (open or down) when you're riding.

What makes a car choke?

Fact is that fuel in the engine is cold when the engine is first started and in order to heat it up, a fuel and air mixture is required, and that's what a choke is designed to do. The choke is usually located towards the upper end of the carburetor, and provides this mixture by stopping the carburetors air supply.

What is full choke engine?

A choke valve is sometimes installed in the carburetor of internal combustion engines. Its purpose is to restrict the flow of air, thereby enriching the fuel-air mixture while starting the engine. Chokes were nearly universal in automobiles until fuel injection began to supplant carburetors.

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.

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.

Can I ride my bike with the choke on?

It's perfectly fine to start the bike with the choke on, then ride it until it warms up a little before turning off the choke. Absolutely no extra stress on the engine, at all. Revving the engine before the bike is warmed up, though, does put stress on the engine, as the oil is cold and lubrication isn't as good.

What does the choke on a lawn mower do?

The will usually be a lever on the handle of the lawnmower or on the body of the engine. Put the throttle lever in a mid-to-high position. The choke helps provide a richer fuel-air mixture to the engine, which helps it stay running until it warms up. Once the mower has been running for a few minutes turn off the choke.

What happens if you ride a dirtbike with the choke on?

Registered. If you have a manual choke, you are causing it to starve for air because you close the plate so it will run rich. If you try to ride with the choke on, you will experience poor performance if it will run at all.
