This is a "G" model, right? I'll bet you a Coca-Cola that you've got a
failure in the (WEAK PLASTIC) "chain" between the knob and the rest of
the rig. 

Take a look at <http://mikea.ath.cx/R-1051/R-1051H-under-2.jpg>, which
is an image of the underside of my "H" model, and compare it with
<http://mikea.ath.cx/R-1051/R-1051B-under-1.jpg>, the underside of my
"B" model. Note that the "B" model uses a nice metal roller chain,
while the "H" (and the "G", I think) use less durable plastic-and-nylon
plastic belts with crosslinks at the same pitch. Read the text at
<http://mikea.ath.cx/R-1051/> and weep gently. Chains are available from
Stock Drive Components. I'm working on putting one in my "H" model to
replace the middle KC drive belt myself. Plan on spending some cash for new
chains, or maybe someone has a parts unit.
