Choke is a technique used in martial arts and grappling. It is a type of submission hold where the attacker restricts airflow or blood supply to the opponent’s neck, causing them to become unconscious.
The most common choke used in martial arts and grappling is the rear-naked choke. This is when the attacker has their arms around the opponent’s neck from behind (similar to a bear hug) and locks one or both hands in a gripping position.
This choke works best when the attacker is in the position of side control, with their elbows bent and the opponent’s chin tucked down into the attacker’s chest. Ideally, the attacker should be able to lock their arms in a figure four grip, with their ebows bent and their hands gripping their own bicep and tricep.
Once the choke is applied, the attacker should make sure to keep the figure four grip and apply increasing pressure to the opponent’s neck until they are unconscious.
What is the symbol for open choke?
The symbol for open choke is the capital letter “O”, typically shown with a circle around it. This symbol is used to indicate that the choke mechanism is open and that the engine is able to receive more fuel and air.
An open choke will allow for a more responsive engine and quicker acceleration, but can lead to increased fuel consumption. It is important to note that the open choke should be used in cold weather or the engine could overheat.
How do you tell if the choke is open or closed?
Generally, there are two ways to tell if the choke is open or closed. First, you can look at the choke lever or knob on the carburetor. Usually, there will be an indicator on the lever or knob that will show when the choke is open or closed.
If the indicator is pointing to the word “open,” this means the choke is open. Likewise, if the indicator is pointing to the word “closed,” this means the choke is closed.
The second way to tell is by listening to the sound of the engine. When the choke is open, the engine should sound smooth and quiet. When the choke is closed, the engine will sound louder and may even sputter or have backfires.
How do you choke a Stihl?
Choking a Stihl chainsaw is a relatively simple process. First, make sure that the chainsaw is in the “Off” position. Then, locate the choke lever, which is usually on the side of the motor near the top of the motor housing.
Push the lever into the “Choke” position and then firmly pull the starter cord two to three times. This will cause the engine to start up. Typically, the choked engine will start with a few laborious pulls of the cord, then begin to run at a slower and steady pace.
Once the motor is running smoothly, push the choke lever back to the “Run” position. Typically, the chainsaw will now start with one pull of the cord. Always remember to refer to the Stihl operator’s manual for tips related to the proper use and maintenance of your specific model of chainsaw.
Why can’t I get my Stihl chainsaw to start?
It’s difficult to pinpoint why you can’t get your Stihl chainsaw to start without knowing more information about your chainsaw. Generally speaking, there are a few common reasons why chainsaws won’t start: fuel issues, spark plug troubles, or a clogged air filter.
First, it’s important to make sure you have the right type of fuel and that the mixture is correct. Stihl chainsaws use fuel that is a combination of unleaded gasoline and two-stroke engine oil at a ratio of 50:1.
Additionally, if the fuel is too old, it may have gone bad, and any moisture in the tank can also prevent a chainsaw from running.
The spark plug is another common issue—it needs to have a small gap between the two electrodes so that electricity can flow through it—so it may be worthwhile to take your spark plug out and inspect it for any signs of physical damage.
If it looks okay, clean it according to your owner’s manual, then re-gap and reinstall it.
Lastly, a clogged air filter can prevent enough air from reaching the engine, leading to a weak spark or an incomplete combustion. To check, remove the filter cover and replace the filter with a clean one if need be.
If your Stihl chainsaw still won’t start, consider getting a professional to take a closer look at the problem.
How do you start a Stihl trimmer?
Starting a Stihl trimmer is a simple and straightforward process. To begin, make sure the trimmer is placed on a flat and level surface. Next, inspect the high-tension wire, trimmer head, and deflector shield to ensure everything is properly attached.
When these components are in place, turn the fuel tank on and prime the engine. Pull the starter rope briskly a few times to start the engine. If successful, the engine should start to roar. Once the engine is running, gradually throttle the engine to get it up and running smoothly.
You can also adjust the position of the trimmer head and deflector shield to find the optimal angle of cutting. After the trimmer has been started and adjusted, you are now ready to begin trimming away.
How do I start my Stihl ms170 cold?
To start your Stihl MS170 cold, you will need to follow these steps:
1. Place the chain saw on a level surface, with the bar and chain facing away from you.
2.Remove the bar cover and check that there is adequate bar and chain oil in the tank.
3. Make sure the on/off switch is in the off position.
4. Slide the choke lever to the closed position, which is located to the right of the carburetor.
5. Place your right hand over the stop switch.
6. With your left hand, pull on the starter cord slowly until you feel resistance (this is compression).
7. Move the choke lever one-third of the way open (position 1).
8. Pull the starter cord briskly and firmly until the engine fires.
9. If the saw does not start, push the choke lever back to the closed position and wait 5-10 seconds. Then pull the starter cord again.
10. If the engine starts, let it idle for a few seconds before slowly pushing the choke lever to the fully open position (position 4).
11. Once the engine is running smoothly, slowly pull the throttle or trigger for a few seconds to increase the engine speed.
12. Replace the bar cover and you are ready to start cutting.
Is full choke open or closed?
The term “full choke” indicates that the choke on a shotgun is completely closed, meaning that the interior diameter of the choke is as narrow as possible. This maximizes the amount of constriction on the shot leaving the barrel, resulting in a tight, concentrated pattern when the shotgun is fired.
However, a full choke does not represent a fixed measurement, and the actual choke on a shotgun will vary depending on the manufacturer. If you need to know the specific level of constriction on your gun, you should consult your owner’s manual.
What happens if the choke is left on?
If the choke is left on for too long, it can cause problems for the vehicle engine and reduce its performance. When activated, the choke blocks off some of the airflow to the engine, which causes it to get too much fuel and not enough air.
This can result in the vehicle engine running too rich, which can eventually lead to a misfire, as well as increased engine wear and decreased fuel efficiency. In addition, the engine may have difficulty starting since it is receiving too much fuel.
For these reasons, it is important to remember to turn off the choke after the engine has warmed up and to keep a close eye on the engine to make sure it is running properly.
What does opening the choke do?
Opening the choke on a vehicle helps the engine to start more quickly and run more smoothly. The choke is typically used when cold starting a car and consists of a butterfly valve that adjusts the amount of air going into the engine’s carburetor.
When cold starting, the choke restricts the amount of air that can enter the engine, which causes more gasoline to be mixed with the air which creates a richer fuel mixture. This helps the engine start more quickly as the rich mixture helps the spark plug to ignite.
Once the engine is running, the choke is opened, allowing more air to enter the engine which has the effect of thinning out the fuel mixture. This allows the engine to run more smoothly as the correct amount of air and fuel are being mixed in the right proportions.
Is it safe to shoot steel shot through a full choke?
It is generally safe to shoot steel shot through a full choke, however it is important to follow manufacturer instructions to confirm. With a full choke, steel shot may deform more than lead, which can cause the firearm to become damaged.
Additionally, there is the potential for the steel shot to ricochet off hard objects like rocks or trees, therefore it is important to use caution when shooting. When using steel shot, a modified or improved cylinder choke should be used to create a safer shooting environment.
It is also recommended that steel shot shells used with a full choke are loaded with a shot size that has been approved by both the ammunition manufacturer and the firearms manufacturer. The manufacturer’s instructions will provide the safest and most effective use of the firearm barrel.
What symbol is choke on Stihl?
On Stihl chainsaws and other power tools, the “choke” is represented by an icon of an open partial circle or the letter “C” with a line underneath. This icon is located near the start switch and is used to trigger the choke to help start the chainsaw when it is cold.
To operate the choke, the user should press down on the switch and move it in the clockwise direction, indicated by an arrow on the switch. When the machine starts, the user should move the switch back to its original position.
This action supplies the engine with the correct amount of fuel and air, allowing for optimal performance and fuel efficiency.
Do most shotguns have full chokes?
No, not all shotguns have full chokes. Most modern shotguns feature a variety of interchangeable choke tubes that can be used to change the degreeof constriction of the muzzle, allowing shooters to better tailor the spread of their shots.
Full choke is just one of many types of choke available for most shotguns, though it is arguably the most popular type as it produces the tightest shot spread and is often used for long-range shooting or hunting.
Other popular chokes include improved cylinder, skeet and extra-full, with the level of constriction getting tighter as you progress along the list. Ultimately, what kind of choke you use will depend on the job you’re trying to do and the type of ammunition you’re using, so it’s important to choose the right choke for you.
What is the choke position on a lawn mower?
The choke position on a lawn mower is the setting that is used to start a cold engine. When you turn the choke lever on, it restricts the amount of air that is let into the engine, which allows for better fuel vaporization.
This allows for a more even mixture of fuel and air to be present when the engine is cold and helps ensure that it starts up optimally. Depending on the model and type of lawn mower, the choke lever may be located near the carburetor or air filter or, in some cases, be represented by pulling a starter rope.
The choke should be set to the “on” position when starting a cold engine and then adjusted to the “off” position once the engine has been running for a few minutes to allow a normal fuel and air mixture.
How do I turn off the choke on my lawn mower?
Turning off the choke on a lawn mower is a fairly straightforward process, but it does vary depending on the model of mower you have. If you have a manual choke, you’ll need to consult your owner’s manual for the exact instructions on how to turn off the choke.
Generally, you’ll need to locate the choke lever, then move it in the opposite direction of the “on” position until it is all the way off. Make sure to keep your fingers away from any moving parts to avoid injury.
Most newer models of mowers now have an automatic choke and will not require you to manually turn off the choke. These are usually activated with a switch and will automatically turn off when the mower is sufficiently warmed up.
If you’re not sure which type of choke your mower has, consult the owner’s manual.
Finally, always be sure to read up on the manufacturer’s safety and operational instructions before starting your mower, and follow them accordingly.
Can you run a mower with the choke on?
No, you should not run a mower with the choke on. The choke is designed to help the mower start by temporarily giving it more fuel. Once the engine has reached a certain running temperature and is idling evenly, the choke should be disengaged.
If the engine is not running smoothly or is bogging down, the choke should not be left on as it can result in more fuel burning without helping to restart the engine. If the mower is having difficulty starting, it should instead be checked for other issues such as a dirty air filter or a loose belt.
Having the choke on for too long can clog the air filter and damage the engine, so it is important to make sure it is disengaged when it is not needed.
How do I start my lawn mower with a choke?
To start a lawn mower with a choke, you’ll need to follow these steps:
1. Make sure all safety precautions are in place before starting the mower, including wearing protective gloves, eye protection and flat-soled, closed-toe shoes.
2. Ensure that you are in an open, well-ventilated area before beginning.
3. Begin by setting the choke lever to the “choke” position.
4. Place the ignition key in the “on” position and turn the recoil starter until the engine starts. This may take several pulls.
5. Allow the engine to idle for a few minutes in the choke position.
6. Once the engine is running, adjust the choke lever to the “run” position. This will allow the fuel to travel directly to the carburetor.
7. Adjust the engine speed control to your desired speed and begin mowing.
Always follow manufacturer instructions for the specific mower when using a choke.
Is it OK to choke down on driver?
It is not recommended to choke down on your driver. Choking down on the club is usually done to increase control and accuracy, but this can be counterproductive when using the driver. Choking down on the driver reduces the length of the club, which limits the golfer’s ability to generate maximum power and distance.
This can lead to a dramatic decrease in the ball’s speed, reducing the overall distance the ball is able to travel. Choking down on the driver also limits the golfer’s ability to rotate the club and make a full shoulder turn, which reduces the timing of the swing and often leads to inconsistent ball striking.
Finally, choking down on the driver raises the club’s center of gravity, making it harder to hit the ball squarely on the clubface. For these reasons, it is recommended to use a full swing and not choke down on the driver.
