I would personally go with one of the Honda Mini 4-Strokes. They've had a 25, 31 and 35cc available. Perhaps check with these guys: http://www.carrprecision.com/Pages/prod02.htm There are other mini 4 strokes around from various garden equipment applications I would likely consider as well, before the Fuji, but again, this is just my personal choice.

I've just never been a fan of the Fuji. The intitial cost of getting into one, plus replacement parts cost being very high, has been a couple of the reasons behind my opinion. Performance, reliability and support would be other reasons, as compared to alternatives that are available.
