If your jet does not measure like the pictured jet do not buy it. There are so many variables regarding the type of jet that could be in the carb. We have no control over jets once they leave us; some customers drill them out, test and tune etc. therefore all jet sales have to be final so customers do not get modified jets. Please measure the jet and if it does not match your jet read identify that jet or send us a picture of the jets (just the jet by itself). Let us know the year, make, model, brand of carb, or if it is chinese copy, if it had a jet kit installed. See also things to check before ordering.
