Finally had a chance to clean this bike up and it looks great. Was a bit ugly with a layer of gunk on the gears and wheels but everything came perfectly clean and mostly looks brand new. A nice degreasing definitely cleared up the issue with the freewheel spinning. It feels fine but when spinning it it makes a bit of a grinding noise. Spins fine and I can't feel any grinding when it's spinning but it kinda sounds like it. Wonder if that's the bearings - not my expertise. Did manage to get the brakes tuned up, through some trail and error. Next up is getting the gears tuned up. I think the cable needs tightened. Other than a little light rust on the handlebars and rear rack holders this bike looks pretty amazing.
