I disagree with John and I only repost because I don’t want you to chase your tail trying to resolve the issue and fiddling with floats etc. the floats will impact the idle circuit, sinking floats will give you a rough idle etc but the rotax carbs at WOT will be utilizing 95% of the main circuit - fuel through the main jet even if that fuel bowl is overflowing with fuel it’s going to keep sucking. If the piston doesn’t open fully (its sticking) that’s going to limit the fuel flow and the air available and it will be out of sync with the other carb and you will get a very rough engine.
EGT is really an indicator of how much energy is being produced in the cylinders, leaner mixtures will cause it to decrease after a peak as less energy is being produced. Rich mixtures also will cause it to decrease but it can also show that no energy or very little is being produced too and that is what I have seen happen in this type of scenario.
