Got my 18RGEU ignition working fine. Still have one issue though. Seems my tacho signal is a bit screwy. Gets up to about 4000 rpm and thats as far as it will go? The tacho is hooked up as per the points style directly to the -ve on the coil so should be working. I suspect there may be a suppressor hooked up incorrectly effecting the signal at higher rpm but haven't checked as yet.
