This switch compensates for the rpm that are lost when you turn on the ac in your vehicle. The ac puts an extra load on the engine that this switch then compensates for and puts your rpm back to where they belong.

What is the black knob under the left carb on a 2005 Triumph Bonneville Motorcycle do. How does it work and how do you adjust it?

That is the idle adjustment. Turn it clockwise to increase the idle speed, counter-clockwise to lower the idle speed. You should not adjust the idle until your engine is fully warmed up, about 5 minutes of running. Adjust the idle speed to just over 1,000 RPM with the clutch in and the transmission in 1st gear. This is the most load your Bonneville will have at idle speed. You may need a bit of assistance for this, take care to hold the clutch in tightly if you lean over to adjust the idle by yourself.

How do you adjust the idle speed on a 1986 Chevy Celebrity?

There is a idle screw that you simply tighten to increase the idle speed or unscrew to reduce the idle speed. look under the hood at the throttle linkage.push the gas and let off of it. when you let off look where it comes to a rest. you will see it comes to a rest against a screw. if you want to idle it down just turn it counter clock-wise. i believe it is star shaped. so a regular screw driver wont work. hope that helps. this should be quick and easy 2 min job

How does a governor work on a semi truck?

If the engine is electronic, engine speed at low idle and high idle is controlled by a computer. If it's an older engine, a set of weights and springs work together inside the governor part of the injection pump to control low and high idle. In between these speeds, your foot does the job on the accelerator pedal.

How do you hook up a tachometer to check the idle on a 1994 Geo metro Also what is the idle speed supose to be?

Most auto parts stores have inductive input tachometers (one side snaps over a spark plug wire, the other to chasis ground) that do a pretty good job for routine tune-up work. Your idle speed will depend upon the type of transmission, emissions system requirements, etc. The idle speed should be listed on a sticker on the underside of the hood of your vehicle.
