The float will not need a different adjustment with E-10, but the fuel jets (both idle and main metering) may. We suggest opening the idle jet 0.002 inch, and the main metering jet 0.001 inch.
Once the idle jet is enlarged, the idle mixture control screw may function as designed.

I am running Ethanol free 87 Octane sold by a new Hy Vee Gas Station in my area, which I am ecstatic about. It seems to have a Bluish Purple dye to it that looks much different from the E-10 fuel.
