Just to remove the dizzy cap, rotor arm etc. All ancient stuff really. Becomes zero maintenance then, although just as messy with long leads everywhere.

A couple of coilpacks with normal HT lead fitments wouldnt be expensive, and are generally much much better. There arent really any downsides, and existing leads should be able to be re-used or adapted.
