Have done some reading but still need some input from the team.
I have a stock 1978 S2L with fuel injection and points ignition. The FI system is now well sorted and I want to focus on ignition. This is a daily/hobby car and not a show/shine car.
The car currently runs well although the idle is a little rough and it stumbles occasionally when hot. The cap, rotor, and points look good (shiny!) and recent. The coil and related bits look as if they are original. Other than a visual inspection and timing light (idle) I have not touched the system.
I am struggling with the choice of maintaining the original system or upgrading to a S3 ignition system.
Would you keep the points-based system with a complete service or upgrade? Why?
I have no experience with points (other than dirt bikes last century) and the system appears fragile (resistor pack? 6V coil?). Is it more robust than I imagine?
If I were to keep the points system, are there any practical upgrades to the system that will improve performance or reliability on a stock engine?
I see variations of this question have been asked many times but I did not find anything that I felt addressed this specific concept.
Looking forward to your thoughts,
