Autolite’s 1100 model has its choke attached to the side of the main body. The 1101 is pretty much the same carburetor, except that the choke is attached to the air horn. The gadget at the side of the bowl with the funny linkage is the accelerating pump.

The other side of the 1100 looks as though it has another accelerating pump. In reality, that second diaphragm is the dashpot for the slow closing throttle. Most dashpots operate on air, but this one uses fuel out of the bowl. The hole indicated by the arrow was formerly used to mount the spark valve, in the days when Ford’s distributor advance was controlled by venturi vacuum.

Underneath the 1100 bowl, we can see how the accelerating pump on the right and the dashpot linkage on the left, hook up to the throttle shaft. The idle-mixture screw is at the left on the mounting flange.

With the bowl cover off the 1100, we see the plastic venturi staked into the main body. Clip next to the choke cover holds the water hose. The idea is to have the hot water heat up the choke coil for quicker choke opening.
