The small Inteks (unlike the large Inteks) seem to have a positive reputation - especially the 850, which seems to be widely worshipped. I haven't heard of the 60 previously - it is one of the earliest of the small Briggs OHV engines, and is out of production.

At this point I haven't laid hands on a small Intek and will be interested in your reports on it. It should certainly have some potential.
