97 xt 90 case problems

[idacal]

I new to this forum so I dont know where to post this so I will try here
I just bought a used xt90 with 3600 hours that needs minor adjustments to the controls one side tracks faster than than the other. I was wondering how to adjust it. and the 2 speed doesnt work either. I have ran a 1045 case but havent worked on the xts so any advice would be helpfull

Zeroing the controls isn't a big deal although I can't tell you how it is done. I have had it done on several machines. On the two speed I have no idea I have never had a problem with the two speeds in my 95XTs.
