I recently bought a rebuilt tripower setup ( not original tripower carbs) with large base carbs for a 350 Chevy. As I tried to install the waterneck I ran into a clearance issue. No big deal, I can fix that. Needed to swap the front and rear carbs bases around but leave the tops where they were. (long story why but its all about grinded parts and clearance issues) Piece of cake. When I took the tops off I noticed that one had a spring loaded rod in the bowl (power valve or intermediate valve?) and the other didn't. My question is does this get removed for the dumper carb conversion or did the part get forgotten in the rebuild? :confused:
