INCREASES THE EFFICIENCY OF MOST CARBURETORS BY AT LEAST 25%   The Carburetor Enhancer Method is a technique for custom-tuning a carburetor. Everything you need to know to increase the efficiency of your carburetor is included in the Carburetor Enhancer Manual . (Vehicle manufacturers are well aware of this tuning technique, but included it in only select vehicles . . . like police vehicles.)   Tools Required to Install & Adjust the Basic Carburetor Enhancer:   • 3/8ths inch drill • 1/8th inch drill bit • 25/64th inch drill bit • Hammer and center punch • Fine toothed hacksaw or tubing cutter • Small fine toothed round file; "chainsaw" file works. • Knife • 9/16 open end wrench • 7/16 box end wrench • Medium slotted head screwdriver • Screwdrivers needed to adjust your carburetor • Tachometer • Vacuum/pressure gauge • Colortune (optional)   • Full Tune Up:   For maximum efficiency of your carburetor and carburetor enhancer method, tune-up your engine and have your drive train checked out. Refer to the carburetor tips in the back of the Carburetor Enhancer Manual.   • Test Carburetor:   Every carburetor that comes to me for Carburetor Enhancer installation gets fully tested. A lot of them fail and have to be rebuilt. It is interesting that nearly all of these deficient carburetors owners believed their carbs "worked just fine". The Carburetor Enhancer Manual tells exactly how to test your carburetor and what to do to fix it.   USEFUL BITS OF INFORMATION:   • Colortune:   My favorite tool to test carburetors is called a "Colortune",. Colortunes make the job quick, easy and accurate. The Colortune will instantly show you the exact fuel ratio of your engine and currently costs less than $50 (instead of a $30,000 engine analyzer).   Colortune is a clear spark plug that allows you to see the color of the flame in your cylinder. A small change in the fuel mixture makes a large color difference. You can tell instantly what your adjustment has done. This saves a lot of time because you don't have the "wait time" required by most engine analyzers after each adjustment.   You can adjust your fuel system as simply as adjusting an oxy/act torch, just watch the color of the flame. Time is important to those people who want to install Carburetor Enhancers quickly and reliably. Colortune comes with a diagnostic color chart and instructions. It has a full range of adapters to fit any spark plug hole.   Instructions on where to buy colortunes are included in the book.         Copyright © 1998-2008 Eagle-Research, Inc.
