My GM811GHD was "sticky" like that as well when brand new. The Wavey Washer fixed it.
One of the biggest improvements I made was when I installed the on my 811.
I have to move most of my mount out, and back in, each night that I use it. (which is a LOT!) If the weather is going to be clear, I leave my tripod set-up, covered, and it stays near perfectly aligned. (But I always PA, and build a new model.)
But the RAEXT allowed me to make "Chunks" out of my mount. In doing so, my balance weight (1 - 11 pound) stays where it is on the CW shaft bar, and the whole Dec axis with the CW is one sub-assembly. So it is in balance when mounted to the RA.
My telescope assembly, likewise, is a "chunk" that when it mounts in my saddle I have a ?clamped as a stop that indexes my D-bar in the clamp and it lands in balance every time. The DVA is underhung on my , and it stops against the front of the clamp.
By doing this, dismantling and reassembling my mount all the time has become a breeze, and it assembles in balance each time. (When I have checked it, it is boringly in balance!)
Incidentally, I balance mine with my wiring harness attached so it is factored in to the over all balance.
(I'm also the guy who uses a digital level to make sure my tripod is plumb to the Earth before assembly. ;^) )
