How to use old school timing light

How do you use a timing light?

Take your timing light and aim it at the timing marks, pressing the button on the light. Because you have the light hooked up to your spark plug means that it has current passing through it every time your spark plug fires, making the light go off and on, creating the strobe effect.

How do you use a dial type timing light?

How does a timing light system work?

When you pull the trigger of the timing light (with the engine running), each time the Number 1 plug fires, the timing light flashes a beam of light. … The strobing timing light “freezes” the motion of the pulley and allows you to see how many degrees before or after TDC the spark is firing.

How do you set the timing?

Are timing lights still used?

still use mine but mainly on carb engines in forklifts and sweepers and old cars not on new stuff.

How do you know if your timing is too advanced?


This causes the fuel and air mixture to ignite and push back against a piston as it is still trying to compress the fuel and air mixture. Timing that is too far advanced will ignite the fuel and air mixture too soon and will cause pre-ignition.

How do you test a timing light?

Do you need a timing light to set timing?

to set your base timing without a light, you just turn the motor over in it’s normal direction of rotation until the mark lines up with where you want it.. loosen up the distributor and hook up a spare spark plug to the #1 plug wire.. turn the distributor until it sparks..

Do you need a timing light?

If your car has a distributor, using a timing light is enough to let you know what is wrong with the car. In general, cars have spark plugs that ignite the fuel in the engine, generating energy for driving the car.

Do timing lights show RPM?

Most of the timing lights available out there work great up to 10,000 RPM. However, if you usually deal with super-bikes, you should get some better option that is even more accurate, like up to 14,000 RPM for instance.

What should ignition timing be at idle?

55 degrees
Idle/staging is typically 55 degrees to ignite the cylinders with a rich idle mixture. Launch typically 50-53 degrees adjusted for an optimum power at launch. Bring the timing back to typically 50-57 degrees for the remainder of the run to restore power.

How do you set initial timing?

How do you know if your ignition timing is off?

Can you set timing by ear?

I call this method of adjustment, “Timing by ear”, because you literally set the timing by sound. It’s not as hard as it sounds (no pun intended). Automotive manufactures do supply ignition timing setting for every application. You could simply use a timing light, and set the engine to that setting.
