I dunno; the guy looks like he cud b a machinist to me. I have to say
he gets more speed outa his than I get from my 35. Of course, I do
most of my machining with a dremel, file, or a grinder. I've not much
use for a micrometer. I will plug the honda Gx35 though, it's really a
great little quiet, reliable engine. Personally, I'm happy with my friction
drive; it's a dam sight less complicated.
