I am building a Bede BD-4C and have been planning to put a Lycoming IO-360 in it. Reading Avgas Replacement: Drop-In Appears Unlikely in AvWeb got me wondering, though. Is a motor that truly seems to run best on 100LL the right choice these days? Would a carburated O-360 make more sense? Is it reasonable to get sufficient cooling air past the fuel injector lines to avoid vapor lock in an IO-360 running mogas?
I am very comfortable with the reliability and parts availability of the Lycoming engines. I don't feel any particular need to become an engine experimenter.
