    A competitively priced 2x2 carburetor linkage with Superlink levers (click more for applications and details). This linkage is sized for use with intake manifolds and manifold adapters that space the carburetors 5 to 5-3/16in apart, including most '2x2 into 4-bbl' adapters, and the Vern Tardell Slingshot 2x2.

    It can also be used for early Ford 4-banger (Model A/B engine) 2x2 intakes, which place the carburetors 5 inches part. See above for typical manifold applications.

    4-banger specialist Charlie Yapp tells us, "Ford Model A and B type engines are mounted in the frame at 4 degrees tilt to the rear so the manifolds have a 4 degree angled mount to keep the carburetors level. The "Equalizer" and "Riley Two Port" dual intake manifolds feature a mixing plenum so the customer can set it up with two functioning carbs linked directly or with a progressive linkage. It will also work quite well, on the street, with one dummy carb at the rear and the functioning carb forward. Why? The reason goes back to the 4 degree tilt. If any raw fuel finds its way into the manifold it will run backwards, giving the liquid fuel more time to be evaporated before it goes into the rear Siamese ports. Of course . . . the raw fuel would degrade the performance and cause a rich situation. If the carbs are set up and jetted correctly there would be no liquid fuel."

    Designed and manufactured exclusively by Stromberg Carburetor, this linkage combines clean, traditional looks with maximum leverage. TwoStep linkage kits come pre-assembled and install in just two simple steps, without the need for extended throttle shafts. These kits are not a ‘one size fits all’ solution. Different intakes use different carb spacing, so we model every kit in 3D CAD and offer different kits for specific intakes. If you’re in doubt, simply measure your manifold spacing – throttle shaft to throttle shaft.

    Check out the following features:

    • Long die-cast zinc SuperLink lever arms. All other parts stainless steel.

    • Extended throttle shafts are not required.

    • New Stromberg ‘Snapback’ throttle return springs, which wrap around the end of the throttle shaft. These chemically blacked, stainless steel torsion springs snap the carburetors shut, yet virtually disappear from view.

    • For a smooth, lightweight look, the swivels are positively fixed by a small e-clip on the back, and the small black set-screws on the front have knurled ends for a strong fix on the stainless rod.

    Every Stromberg TwoStep linkage kit comes with full instructions, and further help with selection, installation and tuning is available at our Tech Center.
