E85 question about filter and Percy's Adjust a Jet

I haven't run E-85 myself but it's my understanding that a E-85 specific carb is necessary. The E-85 carbs not only have much larger main jets, but they also have stainless steel butterflies, SS needles, revised idle fuel delivery and revised fuel curve via a specific metering block that has some pretty sophisticated air bleed modifications. Cork gaskets won't last either. Here's a link to the Quickfuel E-85 carb:
