We have no control over what happens to jets once they leave us; some customers drill them out, test and tune etc. therefore all jetting sales have to be final so customers do not get modified jets. Please measure the jet and if it does not match your jet see our FAQ and read identify that jet or send us a picture of the jets (just the jets by theirself). There are so many variables regarding the type of jet that coulb be in the carb, if you need help identifying it let us know the orifice size number, the year, make, model, brand of carb, chinese copy, and if it had a jet kit installed. See also things to check before ordering.
