Way back in the days when mem were men, and car parts were mostly well made, I used to do it by ear too. But the first, and one of the few, occasions when the timing light was used, it instantly showed a large amount of timing scatter caused by a not very old Ducellier distributor, which went in the bin, to be replaced by one of Joe Lucas's (relatively) fine products, which went on for at least 150k miles.
But the timing light (Guns ons of course) has spent 99.9999% of its life under piles of tools and sundry items. If I run an A series with mechanical distributor again I intend to fit a permanent LED timing light, with switch so that passers by or plod are not perturbed by strange flashing lights from beneath the car. I figure that if it is a fixture I will at least give the timing a brief glance from time.
But I would prefer the diagnostics that come complete with most modern engines. Let's face it, as we get older we all get lazier and at the same time busier with more responsibilities, so there is less incentive to go fiddling about with things by ear, nose or any other organ.
