I am machine two scale models of and air cooled Ottawa engine I have casting for three less 3 fly wheels. The pattern is at the foundry. The first Ottawa engine were like the Gade, that is it exhaust at the bottom of the power stroke as will as the top of the piston travel

Could make an air cooled version of their log saw. They only used one flywheel on the engine.
