TwoStep Linkage 2×2.
Chrome. 5-3/16in spacing

A competitively priced 2×2 direct carburetor linkage, with clean, traditional looks, Stromberg chromed die-cast Superlink levers and a polished stainless steel link rod. Use on intake manifolds with carburetors 5 to 5-3/16 inches apart (see above). If in doubt, simply measure your manifold spacing between the front studs or throttle shaft to throttle shaft. Exclusive to Stromberg Speed Parts, this linkage features ‘Snapback’ throttle return springs – which virtually disappear from view. The swivels are positively fixed by a small e-clip on the back, and the knurled-end black set-screws provide a strong fix on the stainless rod. The linkage comes pre-assembled, installs in just two simple steps and comes with full instructions. Click the other tabs for help with installation and tuning.  

4-banger specialist Charlie Yapp (Secrets of Speed Society) 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 you can set them up with two functioning carbs linked directly or with a progressive linkage. It will also work 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 it more time to evaporate before entering the rear siamese ports. Of course… raw fuel can degrade performance and cause a rich situation. If the carbs are set up and jetted correctly there would be no liquid fuel.”
