Am I mis-reading this? These are the instructions on the Cambridge Lambretta Workshop's web site for setting the timing on a Varitronic:

Setting the timing
There are two versions of the stator plate, there we a very few early versions, these have a slot with A & R marked each side.
All subsequent versions can be identified by having six increments marked on the stator and feature more choice for timing settings.
To set the timing proceed as follows

(1) Early :- These plates need to be set to maximum advance, achieved by rotating the stator plate fully anti clockwise. You can achieve further advance if desired by elongating the slots, but for the majority of applications this will not be needed.

(2) Late -: At fast idle, set the timing to either 21 degrees if using a standard / big bore / Ancillotti type exhaust, or 19 degrees if using any expansion chamber. To do this you need to start the scooter up (checking the flywheel nut is secure) and test where the timing is with your strobe gun. If you need to adjust the timing, take the flywheel off and rotate the stator plate. Rotating the plate anti clockwise will retard the timing, while the opposite clockwise will advance it.

Advance is Anti-clockwise as we all know; don't we? So (1) is right and (2) is wrong.

seems like a typo....Advance is anti-clockwise.
