Lou .... Thanks for the comments ...
ALL of my physical measurements are in approximate fluid OZ based on simple graduated measuring glass.
I am not getting to use any scientific weights & measures equipment here. Also, the engines (19 & 40) appear
to run fine (with the exception of some mechanical issues like frozen contra-piston, pop-off backplate and
wandering needle). I am working to repair these mechanical items now ... I will use the fuel formula above &
will run 40TBR again and verify corrective actions for normal operations ... Flypast111
