That's not right John. The crankshaft should spin relatively freely when it's mounted up and it should spin after you've let go of it. I'm not sure what's happened, and given that the bearings are roller (as opposed to shells) I can't quite work out what would be causing the friction. Equally, the bearings should mean your clearances are reasonably uniform all round, so it sounds more like something's out of alignment. First thing I would suspect is that the locating pin isn't sat right against the right hand bearing.
But hang around here for a while and one of the others will jump in . . .
