Can't get choke cable to stay in any position. Factory adjust procedure does not seem to work. Is there a tricky fix for this?

I believe the plastic housing at the top grips the cable. They can wear out.

Pull the knob half way up, and (if it's still there) lift the rubber cover and turn the knurled collar to adjust the friction on the choke shaft.
