conversion of a small single cylinder 2 cycle motor to run on steam or air. No modifications have been made to the motor! It runs because the impedance in the intake and exhaust ports is massively different. The only work performed was to modify a spark plug by silver soldering a fitting into it so it could be attached to the air supply.
RPM is about 3500 with 100 psig air. Just a demo, I'm actually going to use this motor to demo a steam concept using a simple intake valve and the exisiting exhaust ports to create an efficient "uniflow" steam engine.
