David,
Thanks for the suggestions. I've put a hose into the line, and run water
through both cores and lines. That seems fine. The issue seems to be that
at ground taxi speeds, I'm not getting enough flow to force coolant through
the entire core. It's taking the path of least resistance which is the
upper potion of the core.
There were originally tubes in one end of the cores which forced the liquid
to the bottom. I think that I'm going to have to put tubes back in there to
do just that. I haven't flown it yet with the new cooling set up, so I
don't know if at full throttle, it will be OK or not, but I figure that I'll
be better off if I can resolve the ground issue first.
Regards,
Steve

OK, not a rusty engine. Has something else plugged some of your lower tubes
in the cores?
Could you try blowing compressed air in from one side and see what comes out
the other side (catch it in a plastic bag or bottle or something)? Then,
blow from other side and see if anything comes out the other side.
If don't want to use compressed air, flow some water thru, first from one
side, then form the other, catching the outflow.
Then pour a pan of hot water in from one side and feel each tube. Then
drain, cool it, and pour in from opposite side and see what happens.

"Full of rust"??
If so, you may have plugged up cores.
