The 9 Super 7\u00ae Carb\u00ae makes setting up a multiple carburetor induction system easier than when Strombergs were available new. All that\u2019s required to do so with our kits is a Uni-Syn syncing tool and a little patience. Our 3 Carb kits come with one primary carburetor and two secondary carburetors while the 2 Carb kits are both primary carbs. See our for more information on using the 9 Super 7\u00ae in a 2\u00d72 or 3\u00d72 carb set-up.<\/p>\n

The 9 Super 7\u00ae \u00ae 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.
Our independent tests produced these flow numbers:
3\u2033 of Vacuum \u2013 60 CFM
10\u2033 of Vacuum \u2013 110 CFM
15\u2033 of Vacuum \u2013 136 1\/2 CFM
28\u2033 of Vacuum \u2013 184 CFM<\/p>\n<\/div>\n<\/div>\n
