Much has been recently said about dead stick landings, and I want to make sure I don't have one, so my question will be diverted away to another subject regarding questionable engine performance.

 

I have always had great performing gray head 582, at all throttle settings.  But recently I noticed that on a downwind leg coasting at about 4000 rpm's my front EGT was dropping to about 800 to 850 degrees where the rear one was at about 

 1050. 1000 to 1050 seems normal for my engine on final for each cylinder.  This is the first time I have seen this kinda disparity between the 2 cylinders.

 

Once on the ground, I was static and ran the engine at different rpm's.  Seems that about 3500 to 4000 it will occasionaly "shutter" as in being too rich.  When it does this about 3 to 4 seconds afterwards the egt's on the front cylinder will drop 

 noticabaly several hundred degres. The rear stays steady.  Seems something is cooling the front cylinder down more than the rear.  

 

Full bore open throttle setting are no problem and permormance seems normal.  Since this is a new symptom, and somewhat unusual, I am reluctant to put her in the air until I can figure out whats going on.

 

Any ideas?

Check the jets, the needles and the needle jet.  Sounds like one may be getting worn just a tad, or one may be partially plugged.  Check the float level in the carb also, I had a similar issue with mine.  With the liquid cooled engine, the cylinder cooling wont be different.
