I'm looking to get a return spring set up for twin 4500s. All I see is this. Quick Fuel 49-3QFT Throttle Return Spring Kit For Square Flange 4 BBL Carburetors Im afraid it will be in the way of the bell cranks for the twin carbs. Anyone used this on twin 4500s? I would like 2 springs per carb as I do not want this SOB sticking wide open and once I pass over the acellerator pump cams things get a little sticky.. Thanks for all the help.
