Glad you got it sorted. I've had two rotor arm failures during my time with the Elan and they both went with the same symptoms - car started ok and ran fine at low revs but misfired increasingly as the revs rose. They were both Lucas ones though so maybe it's the cheap copies that fail absolutely.

The rotor arms with the rev limiting action come up on eBay from time to time; they seem to be mostly sold for Land Rovers (?).

To limit at 6500 rpm you would need one marked at half that i.e 3250 rpm.

I don't think the cheapo copiers try to reproduce that type, so if you find one, it will probably be a good one.

Hi Bill,
I do have the rev limiter rotor arm. Unfortunately it's for my original 23D Distributor.
A new old stock 43D came up a few years ago and it was too good a deal to turn down. The 23D was really worn and would have needed quite a bit spent on it to make good. Also I was suffering from bad contacts and running with the copper cored leads. I don't have an issue with the 43D, aside from that stupid riveted rotor arm.
It would be nice to have the appropriate rev limiter rotor arm for a 43D, but did they make them?

Kind regards
Jeff

I'm not sure, are the fittings clearly different between 23D and 43D disties?

YEP!
The 43D rotor arm is longer than the 23D.
