Does anyone have any carb parts surpless to requirements? I am looking for a damper piston to fit one J2 carb.
Just to clarify; it is the big piston that goes into the dashpot you are after, rather than the little damper on the end of the rod that goes down into the piston?
It also depends on whether you have 1” OM carbs or the 1 1/8” HV ones. This table (tidied up by Bruce Sutherland!) summarises the results of a small survey I did on this a few years ago.
