I removed the distributor on a 90 XJS V12 to replace leaking O-ring at base. 90 model year has Marelli Ignition. I can't seem to find a procedure for setting initial timing in service manual. I aligned mark on Dymanic Balancer with pionter where magnetic pickup is and set rotor to 1A plug location. How do I determinr rotation of the slots with respect to the three set screws? Any ideas?
