Obviously, with the electronic set up you can’t use methods which detect when the points open. rubber auto oil seals
Jeep.The way to go about static timing under these circumstances is:
Mark the current distributor position, marking both distributor to clamp
and clamp to block. This will allow you to reference whether the timing
was out, and if so by how much. On the Lucas distributors used for
XPAG, A,B and C series engines, 1mm at the distributor base is 6 deg on
the crank so make sure the marks are clear!
Set the crankshaft to the required static timing point with the rotor pointing towards no 1 plug lead
Refit the distributor cap.rubber auto oil seals Jeep.
Either attach your strobe light to no 1 plug lead, or (if you don’t have a light) remove no 1 plug lead and fit a spare spark plug to it (with the body of the plug suitably grounded to the engine)
Find the approximate position for the distributor by rotating the whole distributor fairly rapidly clockwise (i.e. opposite to the way to the rotor turns) until a spark appears (be it at the light or at the spare plug). You may have to rotate the distributor anticlockwise 20 or 30 deg first before doing so in order to ensure the timed position is covered on the clockwise sweep.rubber auto oil seals Jeep.
Having noted the approximate position, refine the process by using a smaller angle of sweep centred on the approximate position and moving the distributor as slowly as it is possible to do yet still get a spark.

This process may end up with a degree or two of extra advance. In engines with timing marks visible from the top, I would then check by rotating the crank and seeing what the pointers read when the spark appeared. However, this is a luxury for engines which still have the timing marks underneath! In any event, the right maximum advance usually results in more advance at static on a worn distributor.rubber auto oil seals Jeep.
