Think of the servo as a fuel/air mixture controller. The servo determines
the amount of fuel to send to the fuel divider (spider) based on throttle
settings, mixture settings, air pressure, density, and volume.

Pretty good article that describes the differences between carbs, fuel
injection and between Cont. and Bendix fuel injection:

My IO-360 did this a while back. Needed the fuel servo overhauled.

What is a fuel servo?
