Thanks, AC_Hacker! I'm not doing much in the way of varying the speed; running with all the power this little baby will take! There is a small potentiometer on the control board that allows me to vary the speed, with the aid of a small screwdriver.

I'm powering it with a deep cycle battery for now, but my buddy has a small regulated power supply to run it.

I've shortened the capillary tubing several times now. Down to 8 feet of 0.031 now. I'm getting fairly close to the right length, however I might have an issue with pressure drop across the evaporator. I will be adding another port on that side of the evaporator to look for the drop.

Oil migration is definitely an issue, I'm finding.
