Pulleys have very little rotational inertia and so it takes very little (very, very, very little) friction to have them seem like they don't spin. If they're old, you might clean and oil them, but otherwise seal drag will have them acting sluggish. (compare throwing a baseball and wiffle ball, into a high wind, which goes farther).
