Nick, I also had a uneven egt on number one (1) . I rotated the carb about three degrees and problem gone. I use the normal scat tub between the air box and carb. All EGT's are now within 45 degrees. Tex

Tex,
You were lucky; rotating the carb made very little difference on my EGTs.

Is this at full throttle? Mine is excellent once throttled back quite a bit, all within about 30 degrees of each other, which I consider about as good as you can get with a carb.
It's only at the upper end of the throttle setting, full throttle in particular that mine get incredibly uneven.

I have been playing arround with different jets and needle jets and have
come back to the original jets that were in the engine to start. At full
throtle take off and climb they are in the 1150 to 1250 region and not very
close to each other. At cruse arround 2450 to 3000 rpm they are all arround
1275 to 1325. I have a 250 main jet and a 290 needle jet. I only have 28
hrs on the plane and mabe its getting broken in. I will stay at this set up
till I get a few more hours on it. Tex

Linda I have been working on my egt's I have an esqual. This is the first day to fly since changes. My egt's are much better in cruise up to 3000. The fix was to replace the O rings in the manifold. I will take the gasket sealer 2b tomorrow to seal the cracks and around the intake tubes. My plane has 302 hrs flying now hope the info will help will let you know the results.Allan Maxwell
