Hi I'm in the process of fitting my new 123 ignition unit. I've pulled the old one out following the instructions. I've noticed that the locating dog on the new 123 is in a different orientation to the old. The new one has the dog tabs in line with the rotor. Where the old unit is about 30deg difference to the rotor. I believe that doesn't really matter all I have to do is ensure once the dog has been located then all I have to do is set No1 plug lead is inline with where the rotor is pointing. Am I correct?????
