A 1926 hit-and-miss engine is an antique stationary internal combustion engine that fires only when it needs power to maintain speed, cycling freely ("missing") when it runs fast enough.
This was on display at the Mack Open House Car Show 10-08-2022. Here are more pictures from that show.
Here's a video of this engine running.

Speed Control: Unlike throttle-governed engines, a centrifugal governor locks the exhaust valve open or disables ignition when the engine exceeds its target speed, saving fuel and producing a distinct "pop-and-idle" rhythm.
