It's got the look of the Morton M5 about it or vice versa
When I suggested a 90o offset I reasoned it would run smoother but I kinda thought a relatively heavy base would be needed to dampen the uneven cylinder movement.I can appreciate you are building a twin engine as a fun exercise and to look attractive but personally I'd want a twin to have an advantage over a single (whether that be self starting or smoother running) and to me a 180o twin is really little more than a single
