Should my choke be open or closed?

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.

Does the choke let more or less air in?
The choke is a plate in the carburetor that opens and closes to allow more or less air into the engine. Similar to the throttle, the choke plate rotates from a horizontal to vertical position to open up the passageway and allow more air to get by.
How do you adjust lean or rich?
Regardless of whether or not the engine is running too rich or too lean, bring it down to a very lean mixture by turning both screws a quarter-turn at a time, counter-clockwise, then slowly bringing them back up to an equal and smooth mixture.
What position should the choke be in to start?
open position
Normally choke will be in open position, in which valve is parallel to the air flow, and has no effect on the air flow. When choke is actuated by mechanical or by pneumatic method, it rotates an angle restrict the air flow (closed position).
What happens if choke is on for too long?
Leaving the choke on for too long will cause unnecessary engine wear and waste fuel. This is also bad for the environment. The choke is mainly used during winter to help with starting. The engine needs its fuel to be vaporised in order to burn it.

1 notch = Full. 2 notches = Improved modified. 3 notches = Modified. 4 notches = Improved cylinder.
How do I tell if my choke is on or off?

Typical symptoms of a rich mixture are:
- Poor fuel economy.
- Sluggish acceleration.
- Choke not needed from cold starts.
- Sooty or black spark plugs.
- Sooty or black muffler end pipes.
- Strong smell of gasoline when the machine is at idle.
- Uneven running (will often slow from regular idle rpms and then stop)
Is choke position open or closed?
