A perfect analogy is a choir, with each member contributing their part to create the perfect sound. A fuel injected song can be ruined by one person (a single sensor). Owners of early EFI cars are left walking when a certain electronic part is no longer available. This has struck down entire groups of owners, just ask Dodge/Chrysler/Mitsubishi owners about crank sensors, or GM’s “Optispark” dumpster fire from 1992.
On the other hand, modern carburetors make use of the same compartmentalized approach, but the music doesn’t stop if one singer misses a note. Holley and Edelbrock have both perfected their designs, and the aftermarket continues to offer kits to run them on late-model LS engines. Instead of sensors, they operate solely on the engine’s vacuum produced when the pistons move down the cylinders.
Instead of a computer making an educated guess at how much gas you need, a carburetor gives you the exact fuel your right foot asks for. It does this with a trio of singers instead of a full choir, so it's incredibly easy to learn. At idle, fuel is forced between a needle and a doughnut-shaped hole that remains constant.
On either side of these idle jets, fuel is held in small bowls containing floats, which work in the same way a toilet does. These floats are connected by rods that keep the level of the gas optimized as it's fed into the intake. As you are cruising, this ingenious system instantly reacts to your inputs based on the lengh of the rods that connect the floats to the carburetor.
