[CW] Vibroplex Champion Question

Sat Aug 31 12:30:52 EDT 2019

As long as the small pin shaped protrusion contacts the wheel at right
angle to the center of the wheel, it's fine. There's no adjustment for the
front to rear alignment, although you could try removing the damper and
turning it around to face the other direction.
