The number 2 piston on my SU carburetor will not move up and down when engine is being accelerated. When the engine is not running the number 2 piston will not move all the way to the bottom when it is raised by hand. I have switched the piston, spring, and camber from position 1 to position 2 but I get the same results. Everything works fine on number 1 but number 2 does the same thing. I also cleaned all of the parts with carburetor cleaner.
