OK.. one more time on this. <BR>

You cannot possibly get the mass of our engines centered, if you did you would have an engine like the Wankel or RCV. The mass of the cylinder head and header, piston, etc. does have influence on the impulses from the engines firing stroke. But all of our engines used today, OS, YS, Webrea, Mintor, ST and the likes are all basicly the same or near the same in size and mass give or take on ounce or two or mm or two. If your not rotating this mass in the same plane as the c/l of the mount(the crankshaft center) then you are defeating the purpose of a rotationaly dampened mount. So keep the engine mounting beams on the c/l of the mount. Merle has a design that is going to be hard to improve on. Perhaps something like a viscous fluid filled mount like we have in our cars scaled down. But then getting them light enough is an issue. <BR>

You don't need a viscous fluid for the small mass you are trying to dampen. An air bladder would suffice. The weight gain for the valve will be minimal<BR>
