Triggerfish, the messed up calibrations were in the OE (68-71) AVS's only. the later AVS thunders would not have that issue. now you can get the OE AVS's to run like a scalded dog if you put some work into em but for the nth degree of performance there are much better carb choices. but on the early AVS's, He may already have em/they may be required for class rules/he might not want to buy new carbs.
Thanks Robert & not trying to hijack the op's thread, but maybe the carbs just have some dirt in some of the circuits. OR, maybe its the huge content of ethanol & other crap in the winter blend Vegas pump 91. Think we'll try 5 gal of race gas & see if it cures the issues.
As for the op's question, I spoke to Oliver (Competition Carbs) on the phone a few yrs back & he was super helpful.
