Timing marks are usually stamped on the crankshaft pulley (as shown) or on the flywheel (Land Rover for example). Make sure you can read them easily. |   |
Connect the HT pick-up to No1 lead. The inductive pick-up simply slots over the lead. An arrow indicates the current flow to the spark plug... ... as seen here. It’s a loose fit so don’t worry if it moves. Note the Lumenition pack below it. |

Timing on this engine is done with the distributor advance mechanism pipe disconnected. Check spec sheets. |   |
The advance/retard knurled wheel allows fine tuning of the mechanism if necessary. Ensure it moves freely. This wasn’t. Alternatively, the pinch bolt can be slackened off slightly to allow movement if required. Do not over tighten. |
