Can't get a break

Its really not worth the pain. 40 + years old somethins bound to fall of stretch, kink and stick. Shoot I'm 60+ and have had all of that. I'm the kind of person that if its supposed to be in there it should work. Theres a place in Portland Oregon that will go throught it, fix what ever and calibrate it $90 and they pay shipping one way. I don't want to be pulling this thing apart all the time its a pain.
