After quite a bit of back and forth and back again last night....
I think I have both the external pump adjustment, and the metering rod adjustment, about as good as I can reasonably hope to get. I found this to be quite a fussy task.
Thanks to all for the help. I didn’t have time to do the float settings and do reassembly, but should be closing in on completion. I did perform a function check on the accelerator pump with some minerals spirits in the bowl. That all seems good.
