- Fit 5 inches to 5-3/16 inches from carb to carb
- Extended throttle shafts not required
- Fits 4-cylinder Equalizer and Riley Two Port 2x2 intakes (5in)
- Fits most 2x2 adapters designed for 4bbl carb intakes (5-3/16in)
- Fits Vern Tardell Slingshot 2x2 adapter (5-3/16in)
A Premium 2x2 carburetor linkage with rod ends for positive action (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 engines) 2x2 intakes, which place the carburetors 5
inches part. See above for typical manifold applications.
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."
manufactured exclusively by Stromberg Carburetor, the TwoStep linkage
range combines clean, traditional looks with maximum leverage. Each kit
comes pre-assembled and installs 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
modeled 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:Premium kits have opposite threaded rod ends for easy adjustment. Just spin the rod to adjust for the correct lever angles. Extended throttle shafts are not required. Long die-cast zinc SuperLink lever arms. All other parts stainless steel – even the rod ends and lock nuts. Every
kit comes with two 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. Special swivels and bolts
were developed to clamp the rod ends tight. The rounded bolts have a
small blind hole in the head. Simply insert a small rod eg, a hex key,
to stop the swivels turning while you tighten the lock nuts.
