Part # 915116562 Condition New Brand Speedway Motors Sold Kit Details Info Speedway Motors now offers a reproduction version of one of the most popular 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 hot rodders and racers who realized the performance qualities of this timeless fuel supplier. For years customers have been either putting up with poor idling multiple carburetor set-ups or spending hundreds of dollars converting the secondary carburetors so they did not have to idle circuits. Now Speedway Motors is offering our popular 9 Super 7® two barrel "secondary" carburetor with all that work already done. No more wasted money! Speedway Motors has incorporated all of the improvements shown above while maintaining the carburetor's original look. Features such as the , 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® Carb 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 , a , and a little patience. Be sure to include the 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.

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 # must be utilized in order to keep proper fuel pressure at the 1-1/2 to 4 psi range.There are no provisions for a vacuum advance line.

Part # 915116562 Reviews These carbs are great Rated by WT on May 17, 2021 Summary: The throttle shafts on the secondary carbs are shorter than the primary carbs. If they were 1/4" longer then I could have used my progressive linkage but instead had to purchase another style linkage and slightly modify it to get carb arm to bypass the intake.
