Thanks Singo for your input. I have been running 40 psi and thought I could put more in as the load gets heavier.
With the winding and cable system, the service guy said it was on its way out. The winder is quite loose in the connection when I use it, but not sure about the rest of the system. Will read Hairs post and at least have some knowledge to fall back on when it goes in for a service. :-)
