Since when do we in Aust work in US gallons?
Arrrgghh I'd love new bushes...
This is city puttering, often not getting choke right in.  I was getting 31
when I did mainland trip at Christmas.  
Personally I don't trust the lift pin test, due to not knowing how far you
have lifted it, and it moves the needle from its idle spot; I pump the
brakes and listen to the engine.  Currently the idle mixture is spot on by
that test, but due to the inevitable shaft leaks it is richer than it should
be above idle.  I will richen lowest 2mm or so of the needle and see what

  Is that UK or US mpg?

Haven't done any city miles in a P6, years ago I did a run up to
Brisbane in a '67:

Best was about 8l/100km (35 UK mpg)
Worst about 9.5l/100km (29 UK mpg)

SCs can be tuned to run really lean but that may cause long term damage.
I had the mixture dead on according to the lift pin test.

SC had newly lapped valves, rebuilt SU (needle, jet and throttle shaft),
worn chains.  The new throttle shaft bushes make all the difference and
only cost AUS$45 a few years back.  Idle at 500rpm like it's supposed
