RE: Club Mills!
Well it can't work firing sequentially can it (not as a sideport two stroke)-so we are left with either simultaneous firing or alternate firing -and two possible variations for the latter-front two followed by rear two or 1+3 followed by 2+4. If someone has an audio tach they could use it on the You tube video-the revs didn't sound that high-suggesting simultaneous firing to me. I suppose with an in-line setup like that-and the likely crankshaft structure it might be possible to incorporate better counterbalancing than in a single cylinder Mills so vibration of a simultaneous firing setup might not be that bad?
