Mine is a street car and the carb came rich on the primaries and IFR's, and the secondaries are now just a touch rich too. After tuning this carb with an O2 sensor, I now see how difficult it would be to sell a carb and have it dialed in correctly out of the box.
Mine came stock with 68/82 jetting and .033 IFR's. I am now running 62/80 jetting and .031 IFR's for reference. The electric choke is a nice option along with the adjustable secondary linkage which allows you to adjust the seconds from 1:1, 40% and 60% delay for more tuning.
