Garage Sale - Speedy's 9 Super 7 3-Bolt Carburetor

							                        

                                                        
Speedway Motors now offers a reproduction version of one of the most popular 2 barrel carburetors ever used, the original Stromberg 97! Original equipment on '30s and '40s cars and trucks, the Stromberg 97 has long been favored by Flathead builders, hot rodders and racers who realized the performance qualities of this timeless fuel supplier. 
There have been numerous attempts to reproduce this two barrel carb, with little success. "Speedy" Bill Smith of Speedway Motors in Lincoln, Nebraska, took on the challenge to make a great product even better. The 9 Super 7 ® carb brings this reproduction of the original Stromberg 97 into the 21st Century!
Speedway Motors has incorporated all of the improvements shown above while maintaining the 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! 
Aesthetically, the 9 Super 7 ® is nearly identical to the stock unit, minus the large 97 logo that appeared on the side and the patent numbers found on the float bowl area. 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 other similarity that the 9 Super 7 ® shares with the original 97 is the setup and tuning necessary to yield a well-running machine. While perhaps not as simple as bolting on a single four-barrel, the 9 Super 7 makes setting up a multiple carburetor induction system easier than when Strombergs were available new. All that's required is an intake, a linkage system, a Uni-Syn syncing tool, and a little patience. Be sure to include the Secondary 9 Super 7  when installing multi-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 2x2 or 3x2 carb set-up.
