Redline is only authorized distributor of genuine weber carburetors in the western hemisphere. You can
Avoid the risk of acquiring knock-off weber s by purchasing your genuine weber products from redline.
As part of our special relationship with weber, we conduct a series of tests and adjustments on every weber
We sell. We only use factory weber equipment to ensure each carburetor is working correctly, matched for
Multi-carb applications, as well as to ease installation and minimize final tuning adjustments.
Redline conducts the following tests on all the weber s we sell:
we use a weber flow bench to measure both left and right carburetor cfm at wide open throttle to
Insure well matched carburetors.
we measure flow past the throttle plates at idle, insuring pre-adjusted, accurate, air flow at curb idle
we measure each mixture screw port/hole for size and depth, measure mixture screw values of vacuum
At turn out, 1 turn out, 1 turns out, as well as accurately adjust the float height and geometry for
Matched performance.
we assign a stamped serial number to each carburetor that refers to these recorded measurements
(and more) along with the date and technician doing the inspections for any tech support or reference.
