Martin,
Perhaps you have a CHT span warning as I did with my stratomaster
monitor. I have made inserts to the front round openings that shoot the
air up over the cylinders and now have fairly even cooling within 15
degrees. Still a bit high but I'm working on that. I'm considering a
ram inlet on the top of the cowl of some sorts.
Regards,
Jeff R.
