Richer Needles vs. Jet Adjustment

[Bud Krueger <bkrueger@ici.net>]

Hello knowledgeable ones,

       Eric just talked about having the 'richer #6 needles' for his
carburetors.  My Haynes carburetor book would seem to imply that he has HS4
AUD135's whose standard needles are #5.  My question is, "When should one
install richer needles, rather than simply back off on the jet adjustment?"

     To paraphrase Ed, "puzzled minds want to know".
