[Healeys] Carburator needle changes

[glemon at neb.rr.com]

I have a freind who went through this (o2 sensor, computer program to help pick needles) with a triple carb setup he put on his MGC, the procedure Dan describes pretty much describes it, still a lot of trail and error, but I guess at least you have a test other that seat of the pants to see if you are moving in the right direction.  Kind of makes you wonder how much testing they did back in the day to get the "right" needle for various carb and engine set-ups.
