Regarding the clutch saga.......Took it apart, no wear on the clutch material , no wear on the pressure plate but as the previous worn out clutch disc had done the threepiece disc had busted out the springs. In this case totally, so that the splined portion that fits the shaft could spin without turning the disc. The throwout bearing which had been fine last week was cratered, bits of clutch springs littered the inside of the bell. Back to the parts house with my broken bits and pieces I went. The search for the parts commenced anew since as a cash customer they don't keep a history of my specific purchases. After a half hour in the books a discovery was made.... My identical pressure plate specified a one piece Agricultural application disc which doesn't have all those stinking springs. The disc I had which I got last round (identical to the one on it when I bought the used machine) is an old automotive style(1935-1966) that matches the spline count and diameters of the ag disc...but obviously doesn't hold up well in a chipper application. So ,my parts are on there way, won't arrive until Monday (crapola) but hopefully will endure.
