The button profile of the Yokomo button head screws are .5mm taller than the ones in the Associated kits. Try using those (or any others with a shorter button profile) in securing the spur and you should free up the binding in the pulley. This was the same issue with the original BD7 when you were trying to use any spur other than a Panaracer (.5mm less reccess in the spurs).
I had this problem with the original BD7 spur pulley also. Switched to countersunk screws and all good, I did have to shim it a little more though but runs free as a bird now.
