This engine can only ever have one port, it uses the 'exhaust' gasses by cooling them down and forming a vacuum to pull the piston back up the cylinder, it has no forwards power stroke, it is the vacuum stroke that is it's motive power.
I would imagine that you could fashion some kind of flame guard for this that would protect from wind, but, then would you run into problems of suffocating the flame? hmm. I suppose you could make a guard that was both open at the bottom (for air intake) and at the top (for exhaust). Also, do you think this type of engine would benefit from a two-valve cylinder? One valve for the intake of the flame and one valve for the exhaust from the cylinder piped away as to keep a more stable flame?
I made it from plans of a single cylinder engine by Jan Ridders, just modified it to run as a horizontally opposed pair. Used mainly bits from the scrapyard.

That's wonderful work. You have the genius. Great presentation. I've got an ancient electric motor in my list, if you like that sort of thing.
I'm going to look now at all of your videos.
