Just got my car back from Buckhead Imports where it was being checked for an odd noise or two, as well as getting retuned for the 62mm SC pulley. I, too, was told it was leaning out at around 5000 RPM and that I'd need to upgrade my fuel delivery. Ordered the Walbro unit from Needswings and it should be here in a day or so. I'll install that and run back down to BI to get the tune re-adjusted, then I'll have some fun seeing what the new power is really like.

On the odd noises, one appears to be the bearing in the alternator starting to show its age, and the other seems to be the pinion bearing. That one is not real bad, and only makes audible noise above 75mph. Just a little high pitched whine. I'll probably have to have that replaced in the near future.
