Is the Zama LB-S9-81A the carb that came with the Blue Wazoom flatheads?The reason I ask is because I won this on Ebay today. I think it's slightly smaller. After some research I found out the b/w carbs were .870 venturi, and this one is .811 (20.6 mm). The b/w were set up for alcohol. I emailed the guy and this one is set up for gas, so I lucked out. Came with the billet intake and velocity stack. This should work fine on the flathead.
