Thank you. It is a Sturmey-Archer 3 speed. It was the cable in the shifter, just had to move it to the right position and adjust it at the hub. It is working fine now. What kind of oil should I use, there is a oil hole in the hub?

According to the old Dahon manual use 20 wt oil. Filling the hub was a problem initially but I bought an anti-freeze tester from an auto parts store and some clear, lawn mower fuel line. Remove the balls in the tester, cut the fuel line to desired length, bevel one end to fit the hub filler hole.
