Video Description:In this episode of Andy's Auto Sport TV, we show you the basics of tuning just about any single carburetor, and as a special treat, we get to tune Gene Winfield's "The Thing" land speed coupe. Don't be scared - tuning carbs is not as bad as it seems! Video highlights include:
*At 0:30, we tell you the basic tools needed to tune a carb.
*At 1:58, we talk about setting fuel pressure and ignition timing.
*At 4:28, we discuss idle speed adjustment screws, as well as setting the float levels.
*At 6:51, we talk about vacuum settings, idle, and how they affect carburetor and engine performance.
*At 8:54, we make things short and sweet with a quick list of steps to achieve the best carburetor settings for your vehicle.
*At 9:34, we run The Thing on our in-house dyno to see where our adjustments have landed us.
*At 10:09, we sit down and talk about our performance gains and how we got there.

What can you say about a company that has been at the forefront of the OEM and aftermarket automotive industries for well over 100 years? Well, there aren't many companies that can claim that distinction in the first place, so Holley is very much in a league of its own just in that regard. In fact, Holley has become synonymous with American performance, and has manufactured more than 250 million carburetors, all starting with the Ford Model A. Holley carbs became standard equipment on Ford vehicles in 1904, and Holley is still a supplier to Ford to this day. The company brings this history of reliability, as well as its many years of racing experience, to each and every product it manufactures, from fuel pumps to its world-famous "double-pumper" carburetors.
Q: What is a carburetor? Why buy one?
A: Carburetors are mechanical air/fuel delivery systems that were ubiquitous on automobiles before the development of electronic fuel injection. Over the years carburetor designs have been refined and perfected so that now performance carburetors can offer significant performance gains to enhance throttle response, acceleration and top end speed. In addition carburetors are easily tunable by even an average mechanic so that they can be set up for virtually any driving situation from drag racing to road racing. They can also be adjusted to account for things such as altitude or engine displacement. Although relatively simple in design, many people have found that engines setup with the right performance carburetor package can outperform the equivalent motor equipped with fuel injection. If you want to make power the old fashioned way a simple and reliable carburetor is hard to top.
