Thanks, I finally got it somewhat working. I tried Slic3r, and the kickbacks disappeared. Of course, the result was typical Slic3r (wide line spacing that looks awful), but at least it showed me that Cura was still generating code for 1.75mm filament.
I had already done the setting change you suggested, but it's not enough. I had to use the Printer Settings plugin to show me the hidden settings, and use that to tell it that my printer now uses 2.85mm diameter filament. Now everything works as expected, including adding new material to the list. Not sure why that setting isn't normally changeable within Cura... not cool.

Quick answer is that the ratio of 2.85 to 1.75 squared is 2.64X or 1/2.65 is .377. So try 38% flow for a quick fix.
For the proper fix, you need to tell Cura that your printer can accept 2.85mm filament. It's in the machine settings somewhere I think? I remember doing this once and it was a pain. First you have to tell cura that your printer takes that size filament, then you have to choose the new sized filament.
