Subject: Hot #2 on IO-550-N

   Friend of mine is scratching his head over his #2 cylinder on an IO-550-N.  Runs about 40 degrees hotter than the rest, although all his EGT's are nearly the same.  He spoke to a retired Continental engineer, who told him that a lot of the IO-550's had that problem.  My friend has checked all the obvious, baffling leaks, shrouds fitting properly, etc.  He tried putting the oil cooler door on and closing it part way, thinking maybe that would push more air over the cylinder.  No dice.  The problem seems to be not enough air flowing down between #2 and #4 -- that's the exhaust side of #2.
   Has anyone else run into this?  Any ideas how to push more air through there?
