Carb, afr setup running 10 on idle..help

[Chris Holt]

So just completed a new engine rebuild.
AFR gauge is showing 10 (v rich I know) on idle, bedding in engine so samo from turbo to intercooler isnt connected
the carb setup 1.2 main jet .9 air corrector and slightly drilled 2nd stage
air corrector screw doesn't seem to effect the reading. (it's not snapped)
carb is clean (as far as I know)

how can I lean things off at idle?

[Brigsy]

Is itdribbling fuel down the throat of the carb on idle? could be the carb base at fault?

[Chris Holt]

Any ideas whoto best check that apart from buying another?

Air corrector amended to 1.2- still no effect... Everything cleaned- any suggestions?

[Brigsy]

Air corrector will make no difference to idle. If the mixture screw is intact the carb base is probably at fault.
