The Carburetor, Will It Last?
Do you know if your car or motorcycle has a carburetor? Or, perhaps you are trying to figure out how in the world you are going to fix whatever is wrong with yours. The truth is that a little knowledge never hurt anyone. So, let’s take a closer look at what the carburetor is and what it does. You may not even have one to deal with! But, if you do, here are some facts to help you along your learning way about carburetors. What Is The Carburetor? The carburetor is a device on the engine of a car or other vehicle that mixes fuel with air. These are featured on internal combustion type engines. In most cases, the carburetor is no longer used though. Most cars now use fuel injection as opposed to the use of a carburetor. Nevertheless, the carburetor is still used on many small type engines and in older or specialized vehicles. Cars built after the decade of the 1980’s, no longer use a carburetor, but use an electronic, computerized fuel injector instead. In many cases, the motorcycle still used a carburetor. In most cases, engines that use carburetors only use one. But, in high performance vehicles and those with more than four cylinders, there may be more than one carburetor used. But, how does the carburetor actually work? Have you ever heard of Bernoulli’s principle? It says that moving air has a lower pressure than air that is still. That means that the faster the air moves, the lower the pressure will be. The throttle controls the amount of air that is allowed into the carburetor as opposed to the amount of fuel that is used. The vacuum that is created by the carburetor is what draws in more fuel into the carburetor and allows for faster flows of air. When it comes to repair work that is done on the carburetor, it is necessary to learn not only what is wrong with it but also what is needed to repair it and why that is. When you understand how the carburetor works, you can get a better idea of what is needed to repair it. And, you will need to consult a professional if the task is beyond you because not repairing the carburetor correctly can and does lead to more serious problems with the engine down the toad. Manufactures Of Carburetors There are several different manufacturers out there. Most are specialized in where they serve, who they serve or in the exact type of device they make and sell. If you are looking for a manufacturer, consider these. Ford Motor Company’s manufacturer of carburetor’s is Autolite. Japanese automobiles are often equipped with Hitachi, Ltd, Keihin, or Mikuni carburetors General Motors vehicles feature Rochester Carburetor. UK motorcycle carburetors are usually Amal Ltd.

Installing Aftermarket Head Units
Are you thinking about installing your own car stereo head unit? Be sure to read this article and figure out what you will need to do to get it done. Upgrading the sound system is usually one of the first modifications attempted when we talk about car customization. The best place to start is with a good head unit. If you plan to install it yourself, read on for some technical tips from our experience installers. You will need a few tools to do the job right, so start by collecting some screwdrivers (flat head and phillips head), a socket set, wire cutters, wire splitters, butt connectors or heat shrinking sleeves, electrical tape, zip ties, solder and a soldering iron, and some patience. The first thing I would do before installing I would suggest buying the stereo wiring harness for your vehicle application. This will make the installation easier for you if you are a beginner, and it allows for easier replacement of the stock radio (if you choose to sell the vehicle in the future) and swapping or upgrading to a different aftermarket head unit. Begin by disconnecting the negative battery cable from the battery. This will ensure that you don’t accidentally cross any wires and burn out a new piece of equipment. Next, remove the old head unit. If you need to see how this is done on your specific vehicle, you can look up your vehicles application on installdr.com. This is a great resource for seeing pictures of how to remove the head unit. Once it is loose, disconnect the wiring harness and the antenna from the head unit and remove it completely. There are two types of wiring harnesses you can get. There is the universal wiring harness that connects to your vehicles existing wiring harness, and has the unfinished wire ends that connect to the color coded wires of your new head unit. There is also a wiring harness that has a harness on both ends, and just clicks in place on both sides. These are the easiest to install, but can be harder ot find to match your vehicle to the head unit. Most wiring harnesses are the universal type, so we will focus on those. If you have obtained the wiring harness, you will notice the color coded wires in the back of the head unit. The wires on the head unit and wiring harness should match. The head unit wires and the wiring harness wires will be partially spliced for easy installation. There are several good ways to connect the wires. One way is to use butt connectors, which crimp the wires within a connector. These can be picked up almost anywhere that sells/installs head units, or at Walmart, etc. My favorite way requires a soldering iron and heat shrinking sleeves. Twist the wires together tightly. Apply just enough solder to weld the two wires together. Now fold them over parallel to one of the wires. Slide the sleeve over the connection and heat it with a heat gun or good hair dryer. I have had to rewire or repair systems where butt connectors were used, but this could be installer error, and not a problem with the connectors themselves. I have never had any of the soldered connections fail. Once all the connections are made, and the sleeves heated and shrunk in place, I like to take a zip tie and tie them all together. Clip the excess zip tie for a clean finished look. Connect the wiring harness of the head unit to the wiring harness connected to the vehicle. Plug in the antenna (you may find you need an antenna adapter in some applications). Now slide the head unit in place, but don’t attach it yet. Reconnect the negative battery cable and turn on the head unit (make sure the key is turned to the ACC position). It should be functioning properly at this point. If you plan on adding an amp, or have purchased one for this setup, turn the unit off and connect the RCA cables. Run them through the dash to the floorboard and to the amp (more on how to successfully do this in future articles).

A Woman's Guide to Basic Tire Care
Women certainly are not helpless. But sometimes we are a little overwhelmed working a 40-hour week, taking care of the children, cooking, cleaning, and doing laundry. The car is just another added burden when there isn’t a man around to tinker with it. For the woman who finds herself in this situation, this is a short primer on routine tire care that will extend the life of your tires and hopefully make your life a little bit easier. Check Tire Pressure Regularly: Tire pressure should be checked whenever you suspect a problem or at a minimum, seasonally. Symptoms of improper tire pressure include excess wear and squeeling when going around a corner (for under-inflated tires) and reduced traction (for over-inflated tires). Even the temperature can affect your tire pressure. Check your owner’s manual to find where they’ve posted the proper tire pressure (usually on one of the doors) and be sure to keep it at that level. An improperly inflated tire not only wears quicker, it can also be dangerous when stopping and can cause tread separation. You can purchase a tire-pressure gauge at your local auto parts store, use a gauge at the gas station or ask your tire dealer to check it for you. Have Your Tires Rotated: Tires should be rotated every 5000 - 6000 miles. For various reasons, all four tires on a car do not wear the same. The purpose of the tire rotation is to allow for even wear and an extended life for your tires. Some manufacturers recommend “cross-rotation” (moving the right-front tire to the left-rear, etc.). Check your owner’s manual for it’s recommendations. Have your tire dealer rotate your tires regularly. Check Your Wheel Alignment: If you’ve hit a pothole or scraped your tire on a curb, your wheels may have been thrown out of alignment. Symptoms of wheels that are out of alignment are excessive wear (one tire may wear more than the others) and steering problems. You may notice that your car veers to the side when you’re on a straight road or the car doesn’t steer properly in a turn. Unless you notice any of these symptons, you should have your alignment checked annually. Have Your Wheels Balanced at the Same Time They’re Rotated: An improperly balanced wheel will cause a vibration at higher speeds (50-70 MPH) which is noticable in the steering wheel (if a front tire is out of balance) or in the seat (if a rear tire is out of balance). It will also increase wear of shock absorbers, struts and suspensions. If you notice any of these symptoms, you should have your tire dealer take a look. He will need to locate the heavier part of the tire and attach a lead weight opposite it to counter-balance it. Unless you notice any of these symptoms, you should have your wheels balanced every time you have them rotated (every 5000 - 6000 miles).
