The ad reads "Segment valve attached to crankshaft controlling intake valve". Was this simply an advertising writer's way of describing the action of the piston clearing a port or was there something really different about this arrangement?

These engines used a timed rotating disc for port timing. enter 'Rotary Valve" in the search option.Not sure why they wern't more popular ? J.B's comment in a post that they wouldn't run in reverse was a big drawback.
I have posted several of these engs over the yrs, this one posted couple of weeks ago !
