Often referred to as a choke valve, it moderates the flow of air into the fuel-air mixture Its primary use is to restrict the air flow when you are trying to start your piece of equipment This restriction allows for more fuel to be pushed into the combustion chambers
When should I use choke on my lawn mower?
A lawn mower choke reduces the airflow of the engine, allowing for more fuel to be used This process allows the engine to spark and ignite easier, starting up in an instant Choke valves should only be used when absolutely necessary, as they can damage the engine if they’re overused
How do you use a choke on a riding lawn mower?
When it comes to mowing vast swathes of grass, riding lawn mowers gets the absolute tick They’re arguably the most comfortable tools for conveniently cutting grass within the shortest time Thanks to the varied advantages that they offer, riding lawn mowers are pricier than traditional mowers
Is it bad to run a lawn mower with the choke on?
When closed, the choke plate restricts most of the incoming air from entering the carburetor’s venturi This creates additional low pressure in the venturi and also forces air to 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
What is the purpose of a choke on a lawn mower?
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
Should the choke be up or down?
We would say that the “choke” is on or closed This restriction of air flow reduces the amount of air available for combustion which means that the air fuel mixture is very rich The “choke” is off when the choke lever is down or when the choke lever is facing you if your choke is a handle bar mount
How do I start my lawn mower with a choke?
Open the choke all the way if you notice that it has been closed If it has been open, the carburetor may be flooded Close the choke, and pull the starting cord a few times When you get the engine to sputter, open the choke, and try starting the mower
Do lawn mowers have a choke?
The will usually be a lever on the handle of the lawnmower or on the body of the engine 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
Should choke be open or closed when starting lawn mower?
Normally, the choke is closed when starting cold and gradually opened in the few seconds after the engine starts It is left fully open once the engine is running and may not need to be closed when starting warm A typical starting procedure for an engine with a choke might be: Close the choke (usually on carburetor)
What happens if you mow with choke on?
If the choke is left on for too long, excess fuel flows into the combustion chamber, causing it to seize up and stall If this happens, the lawn mower will need to sit idle for several hours to allow the fuel to drain out of the chamber Turn off the choke and try again later
Why does my small engine only run with the choke on?
If a motorcycle or ATV only runs with the choke on, it’s because the richer “choke on” mixture is actually closer to the engine’s normal operating fuel mixture than the leaner “choke off” mixture So when the choke is turned off, the engine gets too little fuel and too much air for it to run and it stalls
What happens if the 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
How do you start a choke engine?
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 position should the choke be in?
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 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 is full choke position?
FULL Choke means the choke is closed This seals off the carburetor’s air supply in order to create a richer fuel mixture needed to start a cold engine Move the choke back to RUN once the engine warms up
Why is my lawn mower turning over but not starting?
The most common reason for a riding mower cranking over but not starting is bad gas, but other possible reasons include: Gas Valve Off No Gas Choke Fault
Where is the choke on John Deere riding mower?
Move the throttle located to the left of the steering wheel into the choke position if the engine is cold Move it into the half-speed position if the engine is warm Some models of riding mowers have a choke knob instead of a choke position on the throttle
