Craig,
There are no marks, save the pointer and the hole that indicates top dead
center. You should have a vernier adjuster on your distributor and moving
the knob will advance or retard the timing.
The recommended timing for a Mk1 or Mk2 Spit is 13 degrees BTDC. Adjust as
follows:
1. Rotate the Vernier adjuster knob counterclockwise until it won't turn
anymore.
2. Position the crankshaft so that the front cylinder is at TDC and ready to
fire. (The pointer on the timing chain cover will be lined up with the
timing mark on the pulley)
3. Rotate the distributor body clockwise until the points just begin to open
(make sure the rotor is pointing to the #1 piston) A test lamp is helpful
for this operation.
4. Tighten the distributor clamp to lock the distributor in place.
5. Rotate the vernier adjuster knob until you achieve 13 degrees of advance
(each click of the adjustment knob is equal to 1 degree of advance)
That's it!
