9 Super 7® Primary Carbs -

1. Features .045" main metering jets and a number 65 power valve, which is the same as a stock 97 carb.
2. Replacement jet access plug gasket use # 91011542, replacement needle and seat gasket use # 91011543.
3. Includes base gasket.
4. The 9 Super 7® Carb ® will operate suitably with fuel pressures ranging from 1-1/2 psi to 4 psi, with a desired setting of 2-1/2 psi to 3 psi. Fuel pressure from 4 psi to 7 psi will cause the carburetor to run excessively rich and may cause flooding. Flooding or leaks caused by excessive fuel pressure do not indicate a faulty carburetor.  A fuel regulator such as # 560-58500 must be utilized in order to keep proper fuel pressure at the 1-1/2 to 4 psi range.
5. Our independent tests produced these flow numbers:
   • 3" of Vacuum - 60 CFM
   • 10" of Vacuum - 110 CFM
   • 15" of Vacuum - 136 1/2 CFM
   • 28" of Vacuum - 184 CFM
