Figure 1. Blinds are on the windows and the monitor is placed at an angle (perpendicular). 1  Place rows of lights parallel to your line of sight (Figure 1). 2  Provide light diffusers so that desk tasks (writing, reading papers) can be performed while limiting direct brightness on the computer screen.igure 4. Monitor with a glare screen. 1  Use glare filters that attach directly to the surface of the monitor to reduce glare (Figure 4). 2  Use barriers or light diffusers on fixtures to reduce glare from overhead lighting.
They all have a choke on the carburetor. What Choke Does. The choke is a valve on the engineâs air intake that reduces the volume of air flowing into the engine on a cold start. Closing the choke valve enriches the fuel/air mixture going into the carburetorâs throat by increasing the proportion of fuel to air.
A vacuum is created that draws air from the carburetor. The airflow through the carburetor causes fuel to be drawn from the carburetor through the intake manifold past the intake valves and into the cylinder. The amount of fuel mixed into the air to obtain the required air to fuel ratio is controlled by the venturi or choke. When air flows through the venturi its speed increases and the pressure drops. This causes the fuel to be sucked into the air stream from a hole or jet.
