William,
I don’t have a Sam James Cowling,
but my cowling from Lancair has an offset in the way the prop matches up to
it. I tried to install my engine with an off set of 1.5 degrees right and
1.5 degrees down. It matches pretty well with the cowling. The spinner
that came with the prop is 13.5 inch diameter at the base and the cowling seems
to be made for a spinner of 14 inches, so I have a quarter inch mismatch to
where the spinner meets the cowl. I could probably try and fair that in,
but I haven’t. A lot of effort and maybe no gain?? It takes
very little right rudder to keep it straight on the takeoff roll and climb out.
Did you offset your engine?

Well, it is at least reserved...
N713BT is mine, or I guess that Mine is now N713BT
depending upon how you want to look at it.
She'll be going to the newly leased hangar in about a
week, but my intake, exhaust, wiring, avionics, and more are all at various
stages on non-completion.
I do have to ask though. It would seem that the Sam
James cowling that I have is set up for a standard aircraft engine with an
offset to match. (one of the nostrils is closer to the prop disc than the
other)
Is this common? (I don't have a plan if it is
not)
