Dennis,

I don’t remember which way = the “B” psru turns.  Is it clockwise or counterclockwise?  I have the = “C” and it turns clockwise.  From the pilot = perspective.

 

How did you arrive at the .6 oz/gal number?  I am using .8 oz/gal, but that is because I am filling = mostly from 5 gal containers and that is 2 oz of MMO and 2 oz of Wal-Mart 2 = stroke.  Same for 50 gal drums, 20 oz/20 oz.
