The RPM solenoid will block the boost signal to the WUR until a preset RPM.

You cannot adjust your boost enrichment or off-idle inrichment with the idle mixture screw. Those areas must be adjusted at the WUR. If you do not have an adjustable (modified) WUR you cannot fix your problem.

Do you know what your fuel pressure is during these events? If not that is where you need to start. Get a fuel pressure reading and an A/F reading throughout the RPM range. Purchase or modify your WUR to be adjustable and then tune away. Start by optimizing your idle CO; everything else will move from that point.
