I have a 1981 Kawasaki Invader with 500 original miles on it. It has been stored for so long that I think the carbs need to be rebuilt because fuel spils out of the float overflow tubes when running and it floods very easily. It has dual Mikuni carbs. Is there any place that I could mail them to to have them rebuilt so that I don't have to do it myself? There is no Kawasaki snowmobile shop around me. Thanks, JH
