FYI on pilot sizes : Pilots 40 and smaller come in 2.5 increments. Larger than 40 come in 5 increments.

often I need to pump up the throttle to get it going.

This is usually an indicator of a cutout problem moreso than a pilot. Cutouts increment by 0.25 but note that larger numbers are leaner with 1.0 being the richest. Changing a cutout will cause the pilot to act in the same direction as the change in the cutout ie: Going from a 2.0 to 2.5 cutout will make the 40 pilot act more like a 35 or 32.5 pilot.

What is the default cutway size on VM38 on ZL500?

2.5 is stock. Slides are expensive!
