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 convey it as much as working temperature. |
| 3 | Intention the timing gentle on the timing marks on the engine. |
| 4 | Observe the timing marks. |
| 5 | Modify the timing if vital. |
Ignition System Upkeep
