David,

Not taking anything personally, i appreciate all help i get here.
I understand what youre getting at with the poor air inflow. My dilemma is partly because, and i assume, other boomer drivers are not having these slow spool up times.
It works for others so im assuming theres something different about my setup.

To further deepen the mystery, on flights 3 and 4, after startup and just at the time i put the hatch on the engine ran down and quit.
The reason was "speedlow".
but it started ok next time around and flew successfully.

Ill speak to wren tomorrow, change the UAT position, and use a felt clunk instead of the orbit clunk as the latter is relatively straight forward to do.
