OK Dan, curiosity has me asking this one. With all the ''hot'' 50 and now 60cc engines out why are you wanting this vintage engine with mechanical linkage et all?
I happen to own two of the 2.6 sized that run very well and had Gary polish the case and bead blast the head, freshen the rings, etc before he closed the doors.
The old Brison 3.2 is right in there power wise with anything of similar size produced today. It may be old but it is no wimp.
