Okay, then, it sounds as if I'll be able to run a blend of maybe 15% to
25% alcohol/gasoline without doing any mods? The carb is easy enough
to re-jet. Any suggestions on which size to use?

Thanks, Dennis and Tim, for your comments.

I wonder if there's a way to remove alcohol or most of it from an
alcohol/gasoline blend? Distillation? Settling? Filtration? Then I
can put the gas into the VW and drink the alcohol.
