What are the procedures for ignition timing?

Ignition timing involves adjusting the point at which the spark plug ignites the air-fuel mixture in the engine cylinder. The procedure typically includes identifying the engine's specifications, using a timing light to check the current timing, and then adjusting the distributor or timing belt/chain to achieve the desired timing marks. It's essential to ensure the engine is at the correct RPM and operating temperature during this process for accurate results. Finally, after adjustments, test drive the vehicle to confirm that performance and efficiency have improved.
