nickki is a stock carb another stock carb is a zenith ,if you want dyno print outs go try it for yourself .Keep playing with those side drafts ,and waste your time.If you don't believe me call Racing Beats,the tech line will tell you they dont work right for a rotary motor .And raising a stock or aftermarket carbs height will change any engines torque curve lower( piston or rotor ),thats simple intake runner theory.
