Sounds like you don't intend to return this scope for a replacement, Dave? This is the one with the dent?
The GSO Crayford has two finger operated screws under the body - the knurled screws. The one closest the body of the telescope is a lock. When you screw that in tight, the draw tube is locked and the adjustment wheel just spins. Loosen that off - you don't really need to worry about it. Just make sure it doesn't fall out and get lost during transport. If you want, remove it entirely and put it away somewhere.
The screw closest to the eyepiece sets the force with which the drive mechanism contacts the draw tube. Too loose and the drawtube slips under its own weight. That sounds like what is happening to you. Just keep tightening it up to reach the minimum tightness at which the draw tube doesn't slip under its weight. Of course, with different weight eyepieces in the focusser, you may have to adjust this tension. The objective is not to have it too tight - puts undue pressure on the various bearings contacting the drawtube. It can also change its behaviour with temperature so you might need to adjust it as the temperature falls.
Does that solve the problem?
