Can you adjust 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.

Initial timing is set by loosening the distributor hold-down bolt and rotating the distributor body. This changes the relationship between the distributor body and the spinning rotor. Twisting the distributor opposite to the direction of rotation advances the initial timing. Next is mechanical advance.
What happens if ignition timing is too advanced?
Overheating. If ignition timing is too far advanced, it will cause the fuel-and-air mixture to ignite too early in the combustion cycle. This can cause the amount of heat generated by the combustion process to increase and lead to overheating of the engine.
How do you know if your timing is too advanced?
In order to flag signs of excessive advance, hard-currency may prevent the engine from kicking back when it starts; rough idle may be caused by too much advance; or detonation may happen as a result of too much advance.
How do I know if my car’s timing is off?

| Naturally Aspirated | 34 – 36 degrees BTDC |
| Forced Induction / Nitrous | 28 – 32 degrees BTDC |
What is normal ignition timing?
The ideal ignition timing for power occurs just before the point where detonation or pinging takes place. Correctly timed ignition will cause peak cylinder pressures to occur around 12 to 15 degrees after TDC.
How do you adjust ignition timing without a dyno?
- At the begining of tune retard ignition on entire map, especially in high boost region.
- Then get good knock detection headphones, and go ride a car.
- At the time of ride step by step advance ignition at every possible engine load, until I hear knock.
Will advanced timing cause hard start?
Hard starting is usually caused by an advanced ignition timing, not a delay in the ignition. In an overly advanced condition, the carb will backfire, while in an overly retarded condition, the exhaust will backfire.

What happens if valve timing is incorrect?
If the valve timing is incorrect, not only will the engine not run, but the piston could smash into the valves, causing catastrophic damage. Usually, the result is bent valves and damaged pistons.
