Hi Chris, and
I can't help on the Stromberg question (UK/Dellortos) but I did fit a Pertronix ingnition system to the Elan, which is essentially the same as the TC Europa. I've also bought one for the Europa but not fitted it yet.
A couple of "heads up" on the deal.
Firstly, if your OEM points/condenser system is fresh and adjusted properly, the cars are good starters and don't normally have any problem in revving smoothly. If you think you've got a poor system then personally I'd make sure that's performing as well as possible before changing it. Things like new plugs/leads/rotor arm & coil won't cost the earth and are very simple replacements. Even if they make no improvement, you'll still have the benefit of new parts to go with your electronic ignition.
Secondly there have been mixed views as to how well the modern electronic ignition works with the olde-worlde rev counters in our cars. Some folks fit Pertronix, etc and have no issues. Some rev counters seem to work fine at first and then become inaccurate and others just don't work smoothly at all. There are plenty of fixes around, including some systems that are supposed to work out of the box. It's been discussed in some depth on Lotuselan.net so you might want to take a peek there, (ok, that's Elans, but the ignition is basically the same)
On my Elan I fitted new internals to the rev counter which solves the problem and over last winter I converted a spare instrument for the Europa as well. The Elan, with Mk1 Pertronix ignitor, works fine, starts well, revs smoothly and I think is more stable at tick-over. So why haven't I done the Europa ? well, the car starts when I turn the key, so it's not at the top of the list yet.....
