A high quality 3x2
progressive carburetor linkage
designed for great looks and a
positive action (click more
for applications and details)
Use with intake manifolds that
put each carburetor 5-3/16th
inches apart. See above for
typical manifold
applications.
Designed
and manufactured exclusively
by Stromberg Carburetor, the
TwoStep linkage range combines
clean, traditional looks with
maximum leverage and huge
versatility. Each kit comes
pre-assembled and installs in
just two simple steps, without
the need for extended throttle
shafts. Our kits are not a
'one size fits all' solution.
Different intakes use
different carb spacing, so we
modelled 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.
Features:
-
Progressive 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.
- 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.
- TwoStep
progressive systems are
designed to ensure optimum
performance and ensure maximum
versatility. The primary lever
has three mounting points to
change when the secondary
carburetors open, and you can
pull the front carburetor or
push the rear one open to suit
individual applications. On
the top setting (as supplied),
the linkage will start to open
the secondary (end)
carburetors at around 50%
primary (center) carburetor
throttle rotation. Lower holes
will open the secondaries
sooner.
- To improve
leverage, the primary (center)
arm was kept as long as
possible without hitting the
carburetor S-jet. It also has
a bigger clamping screw to
handle more linkage torque.
The sliding progressive rod
meets the secondary carb rod
at the top of the lever arm -
not part way down like some
systems. Good leverage is
especially important as 97
multi-carb systems have strong
spring
resistance.
- Special
swivels and bolts were
developed to clamp the rod
ends tight, yet still allow
the sliding swivel to rotate.
The neat tapered rod stops
have discreet set screw
fixings. And the rounded bolt
has a small blind hole in the
head. Simply insert a small
hex key (like the one you use
for the small rod stop set
screws) to stop the swivels
turning while you tighten the
lock
nuts.
- WARNING!
To use this linkage with banjo
fuel fittings (eg. Stromberg
9082K and 9083K), you must add
our 9086K banjo fitting
spacers. Without them, the
banjo and its fuel hose will
interfere with the long
primary (center) lever linkage
arm causing linkage binding or
sticking, which could result
in uncontrolled engine speed,
property damage, serious
personal injury or death.
Always read the instructions
before
installation.
