It ran fine for some time. It has sat for some time and probably with the pet cock open. How many jets are there? I'm going to by a new pilot jet today. Should I consider buying any other jets?
wait... don't buy any jets unless they've been scored or gouged or mutilated. Jets really don't wear out (sometimes a needle jet will, okay).
Just METHODICALLY take them out (2-3 jets, maybe an emulsion tube), soak 'em, blow 'em clean (use an empty Bic pen if you don't have a compressor), re-inspect 'em; and soak all the passages and orifices. You do have a manual now right, right? Go slow, take pictures. Use baby steps.
...and wear eye protection when spraying anything in a carb. important safety tip.
