- Alter the timing. If the timing just isn’t set accurately, you’ll be able to regulate it by turning the distributor. Turning the distributor clockwise will advance the timing, whereas turning it counterclockwise will retard the timing.
Here’s a desk summarizing the steps for utilizing a timing gentle:
| Step | Description |
|---|---|
| 1 | Join the timing gentle to the engine. |
| 2 | Begin the engine and produce it as much as working temperature. |
| 3 | Intention the timing gentle on the timing marks on the engine. |
| 4 | Observe the timing marks. |
| 5 | Alter the timing if needed. |
Ignition System Upkeep
