I like this response. I wouldn't carb it though personally as I am not familiar with them. Keep the fast response of fuel injection. Of course carbing would be cheaper than adding a stand alone unless you go with Megasquirt.

I second the response indicating that 3 mm seals are not required on a NA build.
