Unburnt Fuel Smell

panterashahMember

Hello Everyone,

I have a Holley 650 Double Pumper ( mechanical secondary} carb on my car for a long time, car runs great with instant throttle response. However, It runs too rich with unburnt fuel smell from exhaust especially at idle. My question is that if I were to switch the carb with a vacuum secondary one, will it make a difference as far as exhaust fumes are concerned ?

I am willing to give up some performance for a cleaner exhaust.

Any advice will be highly appreciated.
