Why do engines fire before TDC?
Why do engines fire before TDC?
Timing advance is required because it takes time to burn the air-fuel mixture. Igniting the mixture before the piston reaches TDC will allow the mixture to fully burn soon after the piston reaches TDC. This results in lost power, overheating tendencies, high emissions, and unburned fuel.
Can You detach the distributor from a spark plug?
Detach the distributor cap. On some models you can detach the cap without disconnecting the spark plug wires. If you need to remove the wires at this point, label each wire position on the cap so that you attach the wires in their corresponding place on the cap.
What do I need to know before installing a distributor?
Before we can place the wires in the distributor cap, the first thing we need to know is which direction the rotor turns. For our Chevrolet engine you’ll note that the rotor turns clockwise. Small- and big-block Fords turn counter-clockwise.
How to install a distributor and set initial timing?
Leave a little extra room with the spark plug wires to allow freedom of movement in the distributor. For Chevys, be careful to make sure 5 and 7 are installed correctly. If the wires are accidentally switched, the engine will not be happy. Before we try to start the engine, be sure the distributor is connected to switched power.
What’s the best way to remove a distributor?
To begin removing the distributor, remove this cap. This may or may not require basic tools – some caps have clamps that can be loosened by hand, while others may require screwdrivers or even socket wrenches to unscrew screws and/or bolts holding the cap in place. Remove all wires attached to the distributor.

Where can I find a distributor repair manual?
Repair manuals can be found online, at local auto part stores or by visiting the car dealership service center. Determine which way the distributor rotor turns. The rotor is located underneath the distributor cap. It spins either clockwise or counterclockwise and is referred to as distributor rotation.
