Well, maybe=2E Is it loose on the point can? Or does the point cam just tur=
n back and forth a bit?
Or does the whole mess move side to side?
It normal for the point cam to be able to turn slightly=2E But there shoul=
d be no side to side play; and the plastic piece should be tight on the poi=
nt cam=2E
Side play is usually a sign of wear in the shaft bushing=2E If the plastic=
piece is loose, its probably just time, heat and vibration vs cheap plasti=
c=2E
