Step 2 - Pull out the old points, condenser and rotor. The engine is now mechanically set to operate in the proper firing order. The reason you're doing this is to prevent misplacement of plug wires later and to facilitate removal/replacement of the distributor if that should be required. Mark a line on the side of the distributor housing and continue it onto the engine block. If it's 180 degrees away from that position, crank the engine one revolution back to TDC. Open the distributor cap and see if the rotor is pointing at the #1 cylinder (if unmarked, follow the plug wire to the distributor). Step 1 - Crank the engine to Top Dead Center, as marked on your balancer or pulley. Solid-core wires tend to last much longer but should be replaced when their rubber end caps deteriorate - this keeps the wires from arcing over to the engine block. Plug wires may or may not need replacement depending upon mileage, and we recommend replacing carbon-core wires (resistance wires) after about 15,000 miles on older cars.
You'll want to start with a fresh set of points, condenser and plugs. The ignition is the "bandleader" and everything else under the hood is the "orchestra," so take the time to get it right. The first rule of tuning engines is to get the ignition settings correct. Doing so will cause you to have to "chase" the adjustments with the ignition system and possibly never get things right. The first thing to do in a tune-up is LEAVE THE DAMN CARBURETOR ALONE! It's the very last thing you will adjust so don't touch it. Is all wiring in good condition? Are there any breaks in the insulation? Are connectors rusty or loose?.Are all linkages (choke, accelerator, transmission shift-down) moving smoothly from stop to stop?.Is the fuel system clean (especially the filter) and pumping at the correct pressure? Is there fresh gas in the tank?.

Is the battery up to full charge? Is the generator/alternator functioning properly?.Is the cooling system operating correctly? Aside from keeping the engine from overheating, is it running at the proper operating temperature? Are there any leaks? If there are water hose connections to a plate under the carburetor, are they connected and operating?.Don't allow any of the following to go unchecked or ignored. This is important, since improper operation of some systems will affect the engine's tuning. Spend a few minutes checking out the machinery first. First, Check Out The Basicsĭon't start replacing or adjusting anything right away. Now that we've got your attention, let's start getting the old flivver operating the way it's supposed to.
There is one, AND ONLY ONE, correct procedure to follow when tuning up a car!
