Running rich at idle? Check the float. I always use a brass one. Where is the idle at. Check to see if the throttle plates are past the transfer slot too far. Has the carb been modified? Its possible that the idle tubes have been enlarged. What size jets and rods are you running? It should have a 70 jet,41 rod and a BE secondary rod. What spring is in the power piston? If its too high the rods are beibg pulled up at idle and it will make it run rich. Have the plugs on the bottom of the carb body been epoxied or repaced? If these leak it will make it run rich. FYI you can put a ported vacuum source in that carb also. It just takes time and patience. Set the timing to 12 initial,36 at 25oo and see if it runs rich then. Email me if you want more info.
