Setting the timing will cause more of the HCs to burn off in the exhaust.
Leaning out reduces the HCs and raising the RPM to about 1100 allows your
engine to run at a speed that it breaths a bit better and burns fuel more
efficiently. Regapping the plugs wider would give a fatter spark which would
help but would only work if you had a higher output coil (which would fry
your points system unless you had EI which explains why that later cars with
EI have wider spark gap). I wouldn't bother regapping. Lean out the carb
till it caughs and then turn back a tad. If you can do all this on a gas
analyzer it would be best. Disconnect and plug the vacuum advance.

Well, actually Tintin is a California car since shortly after birth. When
the mercury gets towards and above three digits, he runs much better. Of
course there is no warm-up period, and the timing can't be too far
advanced on the hill climbs, but I think the pre-heated intake must
help the carburation.
Ugly news. I got my 'Smog certificate required' renewal notice.
I thought I had printed off the 'hints to pass smog' from a couple of
days ago, but I can't find it. Could you repost it?
I plan to retard 10 degrees, lean it out until the colortune is almost
blue, take out the air filters, clean and set the plugs and points.
I wasn't sure about regapping the plugs wider. What is this intended
to accomplish?
