Also to add to Den’s post, firing order is 1 3 4 2 – when fitting the distributor with cylinder 1 at TDC using a standard ‘clock’ as a guide, the rotor arm on a normal points dizzy is at somewhere near 20-15 minutes to the hour i.e. pointing forward to the water pump, but with the 123 electronic you may find that with no 1 at TDC the rotor arm is pointing at somewhere near 5-10 past the hour – towards the timing chain end, so don’t panic and think your doing something wrong!!
