We have now found it works on dished pistons equally as well with current petrol available and vac unit fitted.For best performance and tune we advise our electronic evolution version
C-27H7701 The modern demands of fuel economy and performance with the very poor petrol available today often makes a "vacuum advance" distributor a must. The vac unit
fitted on this distributor is the one that works best.
Not for AUTOGRASS racers due to the way they are manufactured because they look like the weights have been modified which the scrutineers do not like.
For 1275 A plus engines see

DODGY DISTRIBUTORS-Cheap china made products available frmo vendors
We’ve seen distributors with all different curves in the same batch. Base plates
that stick and alter the curves, sometimes jamming in full advance. When tested
we had difficulty getting them to run correctly when using a timing light and we
found that the rotor arm and dog at the bottom of shaft was often out of phase
putting the rotor arm in wrong position in relation to the point at where the spark
fired. We also found rotor arms that were hard up against the carbon bush in the
top of distributor cap causing the cap to burn away in middle.
Having tried and tested countless suppliers of imported and British made
distributors we had all ours individually built and tested to prevent costly engine
failures and breakdowns for the following reason - those suppliers were unable
to advise what curves were in them - we rarely found them the same in any
batch! Every part, even so-called ‘Mini Spares branded parts’ are being copied
for financial gain as Minis climb in popularity and value. Unscrupulous
companies can get parts made cheaply overseas, but they lack the technical
knowledge and precision required to make them correctly
