It eventually settles to idle at around 1250 - 1300rpm?
What happens when you rev the motor in neutral? Does it settle back to idle or 'hang' around 2 - 3k rpm?
Is the throttle free-moving as before? Do you have enough freeplay in the throttle cables?
A hanging idle is usually caused by an air leak. Are you sure that all the carbs are seated correctly in the intake stubs and the clamps snugged up nicely. Not over-tightened ... this just crushes the spacer in the clamps.
Any cracking in the intake stubs? Any chance you might have ground through when you were modifying them?
