Default 123 ignition fitted, running v rough

Hi there,
I fitted a 123 electronic ignition into my xk120 saturday, drove sweetly for about 25 miles. Started it today and its running very rough and lumpy! Noticed after the run yesterday it was quite lumpy on tick over but put it down to the fact that the car hasn't been driven in properly years (old distributer would fail after 5/6 miles hence 123) any ideas/?
Regards,
Scott

Hello,

What settings on the 123 did U use, the default does not match a 3.4 of the XK120.
On my XK140 I have put it on 3, but you have to test for the best settings.
Did you adjust it on 10 degrees before DTC, where that the green light goes on.
I have a 123 on all my 3 old jags ( xk140, xk150 3.8, s-type 3.8 ), never had a problem.

regards,
Peter Jan
