1982 Porsche 911 SC Sunroof White

Starts great, runs great, drives great. All gauges work as they should. All lights and electronics work including sunroof. The second hand on the clock does not work. Tuned up 100 miles ago. New plugs, valve adjustment, valve cover gaskets, fuel filter, air filter, oil change/filter. It has turbo valve covers. New clutch cable last summer, clutch adjusted. No broken lower head studs . Brakes flushed 2 summers ago when I replaced master cylinder. Break pads have plenty on them and will include a set.
