What is a good starter engine to make that has a inlet and exhaust at the top of the cylinder? That looks like the direction I want to go with a future more difficult build so I want to start with something along those lines. I will be running it off compressed air or CO2. To further complicate the issue I do not have a lathe but do have a small manual mill with a rotary table.
So what do yall think?
