“Basic timing” refers to the initial setting of ignition timing on an engine that is not running. This setting is typically done according to the manufacturer’s specifications, often involving aligning timing marks on the engine components before starting the engine.
Here’s how it generally works:
- Setting Ignition Timing: Before starting the engine, the ignition timing is set based on the manufacturer’s recommendations. This involves adjusting the position of the distributor or the crankshaft to align timing marks specified by the manufacturer.
- Initial Adjustment: The goal is to set the ignition timing at a point where the spark plugs fire at the correct moment in the engine cycle to optimize combustion efficiency and power delivery.
- Fine-Tuning: Once the engine is running, more precise adjustments can be made to fine-tune the ignition timing using a timing light. This involves checking the timing against specifications and adjusting as necessary to ensure optimal engine performance.
Setting the basic timing correctly is crucial for the engine to operate smoothly and efficiently. It affects factors such as fuel efficiency, engine power, and emissions performance.
