TT 21 problems
sounds like you just don't have your engine tuned well. there is a really good thread on tuning engines, low speed and high speed needles. i wish i remembered where i saw it, maybe someone will know.
i think the gist of it was... adjust the high speed needle, then adjust the low speed needle, then re-adjust the high speed needle again. it may seem obvious, but i believe you need to tune them running AT idle (for idle) and at full throttle for high speed needle. kind of a duh, but i know i didn't figure it out
