Congrats on your first solo event, I've had a lot of fun over the years
running Spits in SFRSCCA events. Don't get discouraged, I've seen Bug's take
top time of day at these events. Most these drivers are very good at what
they do, and have been at it for YEARS, so it will take you a little while
to get to there level. :-)
As far has carbs go, I would go with the 1.5's. They are very dependable
carbs, and great for both on and off the track. If you switch out the carbs,
make sure you put a good header under them, those SU's will thank you for
it. You may also want to think about reducing backflow at the muffler,
Supper Traps work great for autocrossing, just a little loud on the street,
but they make a spit sound sooo good. To insure good response you may also
want to look at sending a little more juice to the spark plugs.
The above will make your throttle foot very happy. After you achieve that,
I'd start looking at making the car handle better. The spit is a blast to
drive with just a few mods. You just need a racing leaf spring in the rear
(flat and stiffer), this will lower the rear of the car about 1 1/2" and
also give you the camber you need. With the back now lower then the front,
you need a shorter and stiffer spring in the front. Most drivers change out
the front suspension parts with GT6's, Add an adjustable swaybar to the
front, and your be running with the best of them and have a very fun spit.
These are just a few tips to help get you fast, stick with it.
Autocrossing your Spit will bring you many happy weekends.

P.S. Just want to say hello to the list, I'm new here. Been reading it for
about two weeks now. This has to be the most helpful list I've ever seen on
the web. I've been around Spits my whole life. I was brought home from the
hospital at birth (April, 69), in a 1968 BRG MKIII, since then my family has
been through at least 12 and is currently down to just three. A 1963 BRG
street car, restored with lots of gofast toys, 1964 SCCA FP Race Car Driven
by my Father (with ALL the toys, hehe). And a 1976 1500 SCCA FP car I plan
to run for at least part of the 2000 season. I look forward keeping up with
this list, its neat to see so many Spit fans in one place:-). I've included
a link to a .jpg of my fathers "#19 FP Dream Cruises Spitfire" rounding Turn
2 at sears point after a victory. (that's me holding the flag). Enjoy
