How do you use a timing gun?
This is useful to you because an engine has timing marks on the crankshaft pulley or harmonic balancer. These can be matched with hash marks on the timing belt/chain cover by using a timing gun. With the engine running and the timing light connected, press the trigger, and the light will pulse with a strobe effect to highlight what your timing is.

Are dial-back timing lights good?
A dial-back light is far more useful. The original dial-back lights employed a simple dial on the back of the light. In this case, you rev the engine to maximum advance and use the dial to line up the TDC mark with 0 (zero) timing on the tab. The dial on the light then indicated the total amount of advance.
How does a timing light work?
The timing light is connected to the ignition circuit and used to illuminate the timing marks on the engine's crankshaft pulley or flywheel, with the engine running. The apparent position of the marks, frozen by the stroboscopic effect, indicates the current timing of the spark in relation to piston position.

How do timing lights work?
The simplest timing lights are self-powered. These lights use batteries in the body of the light that amplifies the signal from the inductive pickup on the plug wire. The most common form of timing lights powered by a simple pair of clamps hooked to a 12-volt battery source.
What does timing light mean on a number one spark plug?
(Image/Jeff Smith) (Image/Jeff Smith) Any timing light will flash when the Number One spark plug fires.
What is the timing tab on a car?
Most engines use a timing tab that is welded or bolted to the front timing chain cover. The tab will offer several hash marks indicating the number of degrees of timing before top dead center (BTDC). These tabs can also display timing after top dead center (ATDC).
How many degrees of timing is required for an engine?
Let’s say the engine requires 15 degrees of initial timing at idle. With the engine running, merely press the advance button on the Innova light to advance the timing until the zero mark on the harmonic balancer lines up with the zero mark on the timing tab. The amount of timing displayed on the light is the initial timing.
What is a dial back light?
The next level up from a basic timing light is what is called a dial-back light. These timing lights use electronics to delay the onset of the spark based on how much delay is dialed in on the light. Original dial-back lights used a simple dial with a timing scale.
Can you use a timing light for ignition tuning?
There are a couple of more sophisticated ways to use a timing light for more advanced ignition timing tuning, but we’ll save those for another time. If you’re just getting started on working with older engines, a timing light is one of the first items that should be part of your basic tool collection.
Is dial back light analog or electronic?
Mostly all dial-back lights are now electronic but there are a few that still employ an analog dial for the more traditional hot rod ders. The one we’re using for this discussion is an Innova electronic dial-back light. It connects just like any other light and uses buttons to advance or retard timing.

And that number is different depending on car models, car makers. But it is not listed on the owner’s manual so you can check on the manufacturer’s websites or listings from professional mechanics. By looking at that number, you can compare what you see to what manufacturer recommendations. For now on, let’s move on how to use a timing light.
What is a timing light?
A timing light is a tool that can check engine ignition timing coming from the distributor. It's got a plastic housing, often shaped like a laser gun from a '70s sci-fi movie. The pistol grip is thought to provide a better handle for precise aiming in tight quarters, but it's probably more likely people expect it to look ...
Why is the timing light called the timing light?
But while it can check for spark, it earns the name timing light because of its primary feature of checking ignition timing. Whether you're aiming for maximum horsepower, gas mileage, a smoother idle, or just the factory settings, a timing light can help you get there. First, run a check to see what the current ignition timing is, ...
How does a timing gun work?
Each time the distributor or coil pack fires through the wire to the spark plug, the timing gun senses the electrical charge and simultaneously fires a light pulse out the end of the gun. This is useful to you because an engine has timing marks on the crankshaft pulley or harmonic balancer. These can be matched with hash marks on ...
What is the red and black on a timing gun?
The red and black are positive and negative for the battery terminals to supply power and ground. The inductive clamp connects onto the No. 1 spark plug wire, and sometimes onto the spark plug itself. Some older timing gun designs are not inductive and instead feature a spring that connects the plug wire to the plug;
Why does my engine make a ping sound?
Engine Knocking – Pre-ignition (or detonation) is the technical term for that ping or knocking sound caused by the fuel and air mixture in the cylinder igniting at the wrong time. If you've never heard it, it's a lot like a metal hammer on the inside of your engine, usually when accelerating or under load. This could be caused by using a lower-octane fuel than the engine requires, or an excessive amount of deposits in the fuel system. Knocking is a serious condition, so try a higher-octane gas with a fuel system cleaner, and check the timing. Newer engines have an antiknock sensor that feeds information back to the engine control computer when pre-ignition is detected, and the computer then adjusts timing accordingly.
How to loosen distributor bolt?
You can use a distributor wrench (usually 9/16 with a right-angle bend in the shaft) to loosen the hold-down bolt for the distributor. Depending on whether your distributor spins clockwise or counterclockwise, turn the distributor gently in one direction or another to advance or retard the spark, then tighten the hold-down bolt again.
