A hit-and-miss engine or Hit 'N' Miss is a type of internal combustion engine that is controlled by a governor to only fire at a set speed. They are usually 4-stroke but 2-stroke versions were made. It was conceived in the late 19th century and produced by various companies from the 1890s through approximately the 1940s. The name comes from the speed control on these engines: they fire ("hit") only when operating at or below a set speed, and cycle without firing ("miss") when they exceed their set speed. This is as compared to the "throttle governed" method of speed control. The sound made when the engine is running without a load is a distinctive "Snort POP whoosh whoosh whoosh whoosh snort POP" as the engine fires and then coasts until the speed decreases and it fires again to maintain its average speed. The snorting is caused by atmospheric intake valve used on many of these engines. (info from wikipedia) I've always been fascinated by hit and miss engines ever since I saw my grandpa's growing up. I made this in order to take a break from working on the PRR S1, this one is based off a 7 Horse Power Galloway, controls: throttle= turn over (run engine slowly) FireGuns: fire engine and simulate governor for slowdown, Group 1: run engine continuously (disable the need to press FireGuns to keep engine up to speed) group 2: turn on gas, FireGuns fires engine, (speeds up flywheels) group 3: bump start (runs engine slowly in reverse) Roll: turns cart, there is a piston inside the hopper (the thing on top) that you can connect to the piece that is supposed to represent water in order to simulate water being used
ATTENTION: opening the exhaust (to make it realistic) takes incredible timing, retracting the Landing Gear opens the exhaust valve manually, making it easier to run, instead of having to time it so that the latch finger holds on to the latch block like an actual hit and miss.
Feel free to make a pulley and connect it to something for it to run (like a saw washing machine, generator or farming equipment)
