Cavelamb,

Thanks for the information. By the way, which Evans are you referring
to in the above post? Which book are you referencing?

Thanks very much.

These engines are more than 13HP but has anybody heard of anyone
powering a plane with a Kohler V-twin?

These 2 engines are the top of the line for both of their series but
look quite workable. The Air-cooled 40 HP engine could loose the forced
fan cooling and probably drop 7 or 8 pounds... The water-cooled engine
only has a dry weight listed and the specs don't say how much water it
holds...

Anyway I found these engines while looking for something to power
another project.
