no when i put it on it tight no movement,then i ride it and check it,it has play got me i had a old 60's shwinn fleet and it did fine with a coaster,im stumped maybe i got a bad rim?
Are you making sure the sprocket is threaded all the way in when you're tightening the bearings? Don't forget there are three bearings in a coaster, you need to adjust the brake arm side (which adjusts the main bearings) then the sprocket bearing cone that only really works when going from braking to pedaling.
