REDLINE JET-PAC’S In
the past couple of years the quality of our fuel has changed drastically
in different regions of the United States. It changes from summer to
winter and seems to be different in Los Angeles or Maine compared to Texas
or Alaska. To keep up with the Government mandated leaner, oxygenated
fuel, Redline has had to increase the size of the idle jets in our
kits 3 times due to the leaner fuel.
A
properly jetted carburetor, that worked well a couple of years ago, may
have lost some of its performance due to today’s leaner fuels. Some
symptom’s of a lean fuel condition are: needing to adjust the idle too
high, rough idle, hesitation or a stumble on acceleration, a flat spot at
around 2500 RPM and/or surging at a constant RPM in higher gears. Along
with leaner fuels, any modifications to an engine to improve
performance can compound the lean effect and require more mixed fuel
volume. Modifications could be as simple as: an opened or larger air
filter, an open exhaust system, or ignition modifications. Some
modifications could be as extensive as a larger camshaft, head
modifications, headers, or increased engine displacement. Also, altitude
& extreme temperature or humidity affects the air to fuel ratio. Any
and all of these modifications are exaggerated when combined with the lean
fuel. REDLINE
recognizes your need to have a variety of jets for all circuits
available when tuning your engine. Our jet kits come with simple tuning
instructions and a variety of jets to cover the stock and modified engine.
We have designed these jet kits from years of experience jetting
carburetors on engines all over the country with all types of
modifications. If you are experiencing any of these symptoms from your
Weber carburetor or simply want to improve the quality and performance
from your engine, one of these kits is for you.

Performance Main and Air Jet Kits For IDF & DCOE |
|
|
These jet kits contain mains and air jet ranges developed
around traditional calibrations, based on Venturi and engine
displacements. Kits should provide a range of calibration flexibility to
help tune most applications |
