Yep...

The Kent 266 is a rather mild profile, David, not too far removed from
Cooper
S. 

Thus, the Lucas 23D (#40819) as installed in early '67 1275 Spridgets
and
1275 Cooper S types should be a pretty
good "generic" starting point. Actually,
there's a pretty good chance it is all
you'll need unless you want to "fine tune"
further on a chassis dyno.

It's a foot to the floor WOT "acceleration" curve for the 1275 Cooper S
running the
original 9.75CR. 

The approx. curve is shown in the 
manufacturer's official maintenance manual, David.

"Teglerizer" site also shows this curve to
some extent on his website per the
post from fellow lister "Pythias".

I will forward to you an email wherein
other manufacturer's produce a "copy"
of the #40819 advance curve.

Peter C. also carries a "41372"
dizzy with 100 of distributor advance
(200 at the crank), but I know nothing
myself of it's advance "rate". You might
find this curve on the Teglerizer site as
well but certainly, Peter would know
something about it.

Considering the cam profile and reasonable compression ratio, almost
all of the stock advance rates are useable
but it seems that of all of them, the 
#40819 advance rate/curve would probably be most generically suitable
considering it's original reason for being?
