Back in the 1970s I attended a national meet of the EDGE&TA in Springfield, Mo. Some of the boys from Kansas brought over their Scott 2-cycle, 1-cylinder vertical engines for show. These engines ran good and smooth. My question is, how was the intake and exhaust on these engines ported? I would like to see any drawings readers may have.
