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.
What symbol means the choke is on?
The choke on symbol for most small engines looks like a horizontal ( — ) or diagonal ( / ) line. It also can simply say ‘Choke’, ‘Full Choke’, or ‘Start’. The off symbol for most small engine chokes is represented by a vertical line ( | ) or the word ‘Run’.
How do I know if my choke is open or closed?
Let’s define the term open and closed – when the choke is restricting air or enriching the fuel mixture, it’s open, when it’s not restricting flow or the air fuel mixture is normal, it’s closed.
How do you use a choke on a Stihl chainsaw?
STARTING YOUR CHAINSAW
Depress the throttle lock and throttle, and move the control lever to full choke (i.e. moved to the limit of its travel).
Firmly press the primer (if fitted) 2–3 times.
Place the saw on the ground.
Once the saw has ‘fired’, move the choke up to the “half-choke” position and pull over.

Should choke lever be up or down?
Does choke need to be open to start?
An engine needs more air as it warms up, so the choke needs to open to allow more air. With a manual choke, you will need to close and open the choke yourself when starting your engine, while an electric choke will control the air supply itself when the engine is started.
In either case, your goal is to get the fuel flowing and get your saw’s engine warm enough to fire.
Set Your Chain Brake.
Close the Choke.
Press the Decompression Valve.
Press the Primer Bulb.
Set the Choke to “Run” or “On”
Pull the Cord Again.
Set the Engine to “Low Idle”
What does 1 notches on a choke mean?
What do the notches on the choke tubes mean? The notches indicate the choke tube constriction. A lower notch count means more constriction (tighter). A higher notch count means less constriction. 1 notch = Full.
What choke is 2 notches?
Improved Modified
What kind of choke has 3 notches?
How many notches is full choke?
Modified chokes normally have three notches while a full choke would only have one. The number of notches can vary between manufacturers, so it is always important to double-check which choke tube you have before installing in your firearm.

What is the pattern of a full choke?
Full: This choke has tight constriction and a dense pattern, delivering approximately 70 percent of a shell’s total pellets in a 30-inch circle at 40 yards. This choke is often used for trap shooting, waterfowl pass shooting, turkey hunting and buckshot loads.
Which choke is the most open?
A shotgun barrel with Cylinder choke actually has no constriction at all. Its diameter is the same as the barrel’s internal dimension. This choke throws the widest pattern, so it is considered the most open choke.
The conventional wisdom has long been that these slugs perform best with an Improved Cylinder choke. Though ammunition is highly variable, and all guns digest ammunition a little differently than one another, I’d be inclined to start with an IC choke. If your accuracy with this choke is acceptable, stick with it.
Is butterfly open or closed when choke is on?
The choke valve will be the first butterfly valve you see when removing the air filter. This valve should be closed because the engine is cool.
What are the 5 chokes?
There are five basic shotgun chokes: cylinder, improved-cylinder, modified, improved-modified and full. (There are several more that are made for specific applications, such as skeet and trap, but for simplicity’s sake let’s keep it at five.)
Lines indicate the size or constriction of the choke tube. A Benelli choke tube with 3 lines (III) is a modified choke. Beretta shotguns that use Mobil chokes will also show 3 lines to indicate modified.
What does 3 stars on a choke mean?
Modified or 3 star chokes
The modified or *** choke is the best medium choke and the most widely used not to mention the most versatile for most types of hunting and, in your first barrel, for many competition specialties too. The choke values in this case are from 4 to 6 tenths, so half that of a Full choke.
