Has anyone had trouble getting to Lean of Peak causing the motor to stumble? On my IO 540 Barrett cold air sump and after consulting with two AI's we think we have found the problem. The intake tubes are not sealing with the gasket only. I'm not able to put pictures up on this, but the flange of the tube sits lower in the collar and the lip of the tube is not constant all the way around.
