Well, maybe. Is it loose on the point can? Or does the point cam just =
turn 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. But there =
should be no side to side play; and the plastic piece should be tight on =
the point cam.
Side play is usually a sign of wear in the shaft bushing. If the plastic =
piece is loose, its probably just time, heat and vibration vs cheap =
plastic.

So question. Do I remember correctly, it's supposed to be tight? And =

I know it could still be a sticking valve, but this first. Thanks, =
