From my experience with the sideways carbs I bought the floats from Pro Systems but a lot of carb manufactures have them. The ones you show should have a left and a right taper towards the back of the car. Once you have the correct floats and have them set correctly I'll bet a million dollars it needs bigger shot of fuel at the hit. Small tube nozzle type squirters (31's) with a bigger cam (Squirter cam). Are you leaving wit your foot on the floor or partly down then full throttle?
