Looking to either service or replace the MK 1 Concentric fitted to my G3C. It is currently fitted with a MK1 Concentric 626 model.
Its a 1960 G3C 350cc engine, wader MAG, fitted with a pancake filter.
If I go for a new carb, should I stick with the same model?
Any suggestions on jet sizes, if I get another 626?
