Zenoah G-50 (Rotax 503 alternative)

Group-

I am about ready to buy an engine for my Tiger Cub plans project. I
am trying to talk myself into a Zenoah G-50 D (free air) engine.
Anyone who has anything good or bad to offer. . . I would sure
appreciate it.

I am also considering a Simonini Victor 1, or the Zanzottera MZ-201.
I can't get either dealer to call me back, however, which is a bad
sign.
