I'm also noticing that after a while when guiding watching my star go east and west along the RA line with periodic error the star will simply keep going west and has sometimes gone out of the eyepiece view. This happens at different locations in the sky. Any idea what's happening and how to fix it?

If the star goes west, it means the RA drive has slowed down or stopped. Have you checked connections? You could also try switching the RA and Dec motors--I think they are the same once you get them off their mounting plates, but you'll need to check this.
Just as encouragement, I have one of these CG5 mounts and it works quite well after stripping and cleaning. I can take 30s unguided subs with 1200mm fl and keep about 60-70% of them, but I needed to get polar alignment spot on and also do a lot of work in getting the worms adjusted; if they are too loose, backlash is terrible and if they are too tight you get strange movements when you use the hand pad for guiding--the scope moves in the wrong direction for a tad and then reverses and goes in the right direction. The best compromise still leaves annoying backlash, but not so bad that you can't live with it.
