[CW] Vibroplex Original Damper Wheel

[D.J.J. Ring, Jr. via CW]

The Original damper wheel moves around, I just tried to take two of them
apart, I cannot do it with my fingers, the nut on the back will not loosen
all the way.  Same with the other key.

I have never had the damper wheel fly off.  I have had them tighten up, but
I just back off on the forward screw.  I do not remember if this was other
people's bugs or mine, but I check my bug often.

Damper wheel moves.
Weights tightly screwed on.
Adjust dash distance.
Adjust dash tension.
Clean contacts with stiff paper.
Check for 10 solid dots.

If something doesn't sound right, I investigate.  Common malfunctions are
dirty contacts, poor ground due to ground terminal being loose, hot
terminal underneath straps dirty or loose.  Dot U spring loose on
Vibrator.  Oil on dot lever tension spring on deluxe post 1980 bugs.
Broken or loose ground strap on deluxe pre 1980 models.  Oil or grease put
on trunnion pivots:  clean off!!
