I suppose it being Lucas, rather than Bosch, would change the enjoyment
factor quite a bit.

Yup. What better way to spend a sunny saturday afternoon?

I like machines that I can see working, myself. Dwell relates directly
to points gap, can be visualized, and is obvious when something is
mechanically wrong - because you can see it. Not saying it's a better
technology than the ECUs, but it's certainly more approachable.

You like the 'wrench knuckles' too ??? ;-)

Actually it wasn't too tricky. Lovely vernier timing adjustement. ( Rover called it the 'octane
selector' on the 2000TC ) Haven't seen a Bosch close-up to compare sadly.

Thankfully those were my student days. I was quite unusual in even being a student with a car back then
! Today they all have one and unlikely to be as much as 10 yrs old.
Self-maintenance was the only option. I reckon I've done pretty much everything on a car bar welding
and a gearbox strip / rebuild.

I still have a sneaking regard for this. It's so much more *tangible*. I wouldn't like to rely on it
for my everyday travel though !
