My E-type dies after 15 minutes

[Jcrosby (Jeffrey Crosby)]

Before you jump towards a Petronix, there is a lot of good info on the site of different ignition systems. This thread listed below has some good discussion; you’ll have to wade through quite a bit of blither, but you’ll get a better idea. In a nutshell, it seems a 123 is often a better choice.

Best Ignition System?

Though timing seems important too - specifically how that timing varies at different engine speeds. The curve on my S2 was pretty conservative (possibly due to emissions concerns) and I changed the springs to create a much steeper curve that I feel produces better performance (seat of the pants). That was on a points ignition and was a rather inexact process using a Sun Machine but a programmable ignition would seem to me to be a much easier and surer way to get there.
