A bit too warm for comfort, although I did have good smoke... top seems about right. The bottom needs to be fattened up a bit, but I was having trouble with it bogging and not wanting to idle if I did so. It only has maybe half a gallon on it now, and is still so tight I can't turn it over in the chassis when it is cold.
If richening the bottom makes it boggy, lean the bottom instead. Then back off the idle to get rid of the "zing"

May need to richen the top just a hair after doing this.
