Loïc Jr, [11/27/2023 1:39 PM] 484. Two Plain 9 Super 7® Carbs to 4-Bbl Intake Manifold Adapter Kit $ 989 This kit allows you to put Elevemotors’s 9 Super 7® carbs on your standard 4 bbl intake manifold. It includes two carbs, the adapter, air cleaners, linkage kit, fuel block, fittings and red fuel line. Assembly required. 2-Barrel to 4-Barrel Intake Adapter – Allows you to mount any Stromberg “97” or Holley “94” three bolt carb to a small 4v (WCFB) Carter AFB or Holley 4 barrel carb intake. This adapter comes with mounting bolts and two 3-bolt carb mounting gaskets. This kit measures approximately 10 1/2″ from bottom of the adapter to top of the air cleaners. Spacing for two barrel carbs is 5-1/4″ center to center. Thickness of adapter is 1-5/8″. This kit uses two primary carburetors and idles on both. Non-Progressive style linkage included. It does NOT come with the intake manifold to adapter gasket. 4 Barrel Carburetor Base Gasket NOTE – There are no vacuum ports on these carbs so you may need to tap into the manifold for a vacuum source. 9 Super 7® Primary Carbs – Elevemotors Motors has incorporated many improvements in the 9 Super 7® while maintaining the Stromberg 97 carburetor’s original look. Features such as the choke assembly, accelerator pump, main jets and cosmetics have all been faithfully retained. Additionally, each carburetor is individually flow tested and inspected for leaks. Perfection is the result! Upgraded internal parts include; the float, needle, and seat. Jetting and power valve settings remain as they were for the original 97 carbs as well as the cfm and vacuum specs. The 9 Super 7® Carb makes setting up a multiple carburetor induction system easier than when Strombergs were available new. All that’s required to do so with our kits is a Uni-Syn syncing tool and a little patience. Be sure to include the Secondary 9 Super 7® when installing 3-carb setups. Our 3 Carb kits come with one primary carburetor and two secondary carburetors while the 2 Carb kits are both primary carbs. See our Multiple Carburetor Tech Tip for more information on using the 9 Super 7® in a 2×2 or 3×2 carb set-up. On the primary 9 Super 7® carb the throttle shaft extends from carb body .983″ and has the hole on the end to pin the linkage. There is a brass sleeve that the throttle shaft rotates in that extends from the carb body .400 and this leaves the useable throttle shaft length of .583. There is sufficient room for progressive linkage and the manual throttle linkage that rotates over the sleeve. All-new tooling for crisp, flawless castings New aluminum base assembly allows for cooler fuel temps and better fuel efficiency as compared to the original cast iron design Stainless steel screws and hardware Choke assembly, accelerator pump, and jets have all been faithfully retained and accept standard Stromberg parts Features original Stromberg 0.97″ venturi diameter Modern Nitrophyl float and Neoprene gaskets Original troublesome needle and seat replaced by a Grose-style fuel inlet valve to better cope with higher fuel pressures and improved high speed running Will not stick or dribble like the old Viton-tipped needle and seat setups Grose-style jet valve won’t corrode in modern fuel, something the original needle and seat units can do Comes with a No. 65 power valve and 0.045″ main jets, identical to the stock 97 Extended brass throttle shaft to simplify multi-carb linkage 9 Super 7® Primary Carbs – Loïc Jr, [11/27/2023 1:39 PM] Features .045″ main metering jets and a number 65 power valve, which is the same as a stock 97 carb. Replacement jet access plug gasket use # 91011542, replacement needle and seat gasket use # 91011543. Includes base gasket. The 9 Super 7® ® 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 to keep proper fuel pressure at the 1-1/2 to 4 psi range.
