Went back to scatt tube and removed airbox deflector and problem solved.
Dave, does that mean back to the original EGT before your changes (wide
range of EGTs) or does that mean you are back to the more evenly spaced EGTs?
Linda and I put the vane modification in her air box outlet that leads to
the carb (still using scat tube) and her EGTs then were much closer on
spread from highest to lowest (like maybe 60 degrees) than before the mod.
Prior to that we had tried twisting the carb and also the smooth hose with no
real help. We will have to wait to see if cooler OATs have any real effect
on the EGT spread.

Buz, did you position the vane vertical or horizontal? Tex

Tex, it is vertical, starts near the beginning of the air box out put tube
and extends about 3/4 inch past the end of that tube into the scat hose to
the carb. It is also exactly streamlined with the airflow. My plan was
to slightly deflect it to one side or the other if the EGTs were still uneven
from one side to the other. No need to do that - it helped as is. The
vane is held in place with two pulled rivets, but at some time in the future
the plan is to either replace the pulled rivets with AN ones, or epoxy it
in place. I don't want them working loose and have a part of them going
into the carb. Hope this helps.
