what other currently available engines have been successfully used in

the engine problem seems to provide the most unsolvable dilema when
attempting to build a small aircraft. I'd hate to think that the
prospect of engine conversions was passing.

A very active group of fellows in Poland are using Moto Guzzi M/C
engines as well as BMW's. Honda marketed a similar type of engine that
has been tinkered around with a bit but most likely needs a different
crank or cam. I have read of one person using a small Honda auto
engine that he replaced the crankshaft in order to get more thrust at
lower rpm's. He didn't use a PSRU. Couldn't on of the three cylinder
Geo engines be modified with a custom crank or cam to do this with the
right prop? Water cooling has advanced a lot in the last few year's
with very light weight radiator's.
