When ordering you might be very spesific with them ,call and actually talk to some one.I bought a kit from Jim carter ,which for the most part is o.k.But my w-1 carb kit was suppose to be complete.So i never checked it out till i went to do the rebuild and had the carb tore down.Lo and behold the excelerator pump was not even close and some of the needle valves were missing.For now I put in what would fit and replaced the original part back.Good luck and ask a few questions before purchasing a kit.Chad
