My EGT's at WOT are a little high 1250 F, while the cruise is a little
rich 1200 F.
Jabiriu 2200, serial # 988, solid lifters, Bing 40mm carb, no tuning
kit, main jet 255, needle jet 276.
Does anyone know how much the WOT EGT's would go down by raising the
float 1/32"?
Then I can lower the needle to lean cruise.

The Bing manual for the carb says NOT to change the float (from what
they suggest) to cure a problem, but to cure the problem by
addressing either the main, the needle jet or the jet needle,
whichever "neighborhood" the problem resides in (my analogy). I've
read of guys who have adjusted the float height, but Bing says not
to. Are you sure you have a "lowerable needle"? Mine is not, having
only one groove for the snap ring.
