C77 Jet sizes?C77 Jet sizes?I have been chasing a problem with my 1967 C77 for the past year. It seems to be running badly over rich. I get one or two runs from a set of plugs before they are so fouled that they wont fire any more.
I have overhauled the carb, checked that it has the right jets (by number), adjusted the needle and it STILL turns the plugs "black and fuzzy" after an hour or two of riding. All I can think of is that somebody may have drilled out the jets or that the jets are badly worn. Does anybody know the orifice diameter in each of the OEM jets? At least I could measure these and make sure they are actually the right size.....
