SU Idle speeds

["MSLishego" <mikesl@tartan.sapc.edu>]

Hello all,
        I recently swapped SU manifolds on my '74 B with HIF's to rid myself of
some intake leaks.  The leaks are gone, but I've run into a tuning problem.
        My idle speed while on choke is about 1000 rpm, but it jumps to 1500 rpm
when the car warms up and I drop the choke.  Any idea what I'm doing wrong?
 The colortune says I'm ok, but I'd like to hear what the MG Masters have
to say...Thanks!
