Small, compact, smooth running hit & miss engine.
This engine does not have a pulley. First I tried driving the Baker Fan from the small diameter drive shaft extension.
Then a 3D printed 20mm pulley (with a push-on fit for the crankshaft), which spun the fan faster placing additional load on the engine.
