This is a very insightful and thought provoking topic and I enjoyed
reading it. The HF engine mentioned is a knock off of a Robin engine
and is actually a fairly well made engine. I’ve found it interesting
to see the larger HP rated Generic and B&S V twin engines turning up
in aircraft projects and the re-drives fabricated for them. They’re
less expensive then the imported engines and do a good job for their
purpose. What they lack though is the 40 to 50 + HP range. This
however has yet to stop innovative approaches and solutions to the
problem by end users, i.e. us.

I bought the 6.5 hp version 2 years ago for the gocart. Nary a problem,
starts usually on the first pull and runs good after a decent warming
period on half choke. Now its coupon priced under $103...
