PSA: Check your governor cable tension if your car is bouncing on the rails
Had a service call last Tuesday in an old building downtown. Car was shaking bad on the way up. Thought it was guide shoes at first. Turned out the governor cable was loose and slapping the rail brackets. Tightened it up and the ride smoothed right out. Anyone else run into this on older setups?
And @bettyk53 is spot on about the loose cable thing, it's wild how such a tiny simple fix solves big problems in all kinds of stuff... reminds me of how a loose screw on a door hinge can make the whole thing jam up.
