    He certainly knows more than I do about carbs.

    I would suggest to you though that your needle and seats have a tendency to leak through as they wear out, and the higher the pressure, the sooner they wear out. A 50 PSIG is a high pop off pressure. The old gp's (97-99) have high pop off pressures as well and are notorious for having rough idles due to leaking needle and seats.

    Kind of wondering if there is another combination of needle and seat with a different spring (and jets)that could give you the results without all of the grief. Now that would be something that you might be able to discuss with him.
