Many people are confused about the sizes of the NU50 Petcock and so I took out the petcock on my 1983 junker and measured everything. It uses a 22mm wrench (O.D. nut) to remove it, and it has 14 x 1.50 mm threads. I also checked my 1983 NC 50 2-speed and it was the same size. Earlier models may have a smaller petcook.

My 1982 Urban has a 16mm x 1.5mm thread size... I tried a 14mm x 1.5mm, will NOT fit.

82 & 83 NU50 and NC50 are 16mm x 1.5mm as stated above. original poster is wrong.
