Bingo. On my old Tomahawk, I had to dip the tip of my index finger into
engine oil and spread it on both yoke shafts about once every six months
to keep everything moving easily. The difference between pre and
post-lube stiction was noticable.

I'll bet a little lithium grease would work better, longer, and be less
mess.

Of course, you seldom will have a bit of lithium grease on your dipstick,
when you need it! g
