Kirk,
The new David Cook (DC Carbs) 3310-1 carb I'm trying out has a PV in the front and blocked in the rear. It is not the .025 over bore version and had a nice fuel curve. Of course the jetting is not square F to B , but the fuel flow- A/F ratios look good. Up to now I've always run a std bore # 4779 750 by Da Vinvci. I'm not a big fan of PV's but this is the way he sent it and I'm going to try it that way. It does stay clean when idling and at low RPM.
