Does anyone know how i can get my recently rebuilt 4 corner idle 850 dp float to stop sticking? Is thete a good chem that i can add to my gas? Really dont want to pull it apart but i will if thats the only solution. Doesnt seem to be any rhyme ir reason. Does it at an idle wide open and anything inbetween. Intermitent....runs fine %75 of the time....gotto tap the bowls to unstick them.
