Doug,
You found a trained 3 foot monkey with 12" fingers? Is he/she for rent? If
so, how much?!

I have experienced almost complete lockage of the throttle and prop
controls. Could not find any binding in the tubes forward of the front
cockpit controls. The binding was bwtween the front cockpit and rear,
somebody had tightened the control lock in the rear and moving the front
bent the tubes between the two. My advise is to remove the rear control lock
knob.

Cy,
Most of the time the problem is not with the inner cable assembly, the
problem is caused by the soft copper shield/tube which the cable assembly
runs in. The shield becomes dented or kinked and each dent or kink adds to
the friction placed on the cable, soon it becomes stiff and unusable. If
the dent or kink is within the travel range of the end rods the assembly
qiuckly becomes nearly unusable. The outer shield or tube can be easily
replaced with std copper tubing of the correct size. I built one up from
scratch for the mini yak and I think I used 7/16 copper tubing. If you do
need the cable assembly it's doable by contacting the McFarlane company.
They can swage the SS rods onto the cable but at that time they did not have
the tooling to cut the metric threads on the rod ends.
Like many jobs getting the part out to work on it is 99% percent of the
battle, this one is no different, you will be talking to yourself before you
get the control R&R'd, so do it on a day when you have your midget
contortionist buddy visiting your hanger. Or maybe wait until the circus
comes to town to recruit some help.
Hope this helps.
Always Yakin,
Doug
