Yeah, I kinda knew what they were, but had a brain fart as to the term. 
Thanks.  I have emailed Tracy as to send it back and to try to determine 
what went wrong.  Seems this kind of stuff always happens around Sun & Fun

Gotta admit, I would rather it happen and be discovered now, even though I 
hate the added delay of first start of my newly built engine.  So it goes.

All the best,

Chris
