HB engines??
And don't leave out that Helmut Bernhardt was born "at a tender age".....
I had a 61 and a 40, both the Perry Ported versions. Nice engines for sure. The 40 was kind of "stocky", i.e. wide across the crankcase, etc.
I think Mecoa bought the tooling so I suppose the engines available now are of decent quality also.
