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.
Getting the fuel-air mixture just right is the job of a clever mechanical gadget called a carburetor: a tube that allows air and fuel into the engine through valves, mixing them together in different amounts to suit a wide range of different driving conditions.n summary, then, here's how it all works: 1  Air flows into the top of the carburetor from the car's air intake. 2  When the engine is first started, the choke (blue) can be set so it almost blocks the top of the pipe to reduce the amount of air coming in (increasing the fuel content of the mixture entering the cylinders).
