Yup, a Honda GC engine. Belt driven overhead cam, like 99% of automobile engines. I understand the rubber belt runs through the crankcase oil; gets an oil bath.

Definitely a fan of the vertical cylinder configuration as opposed to everything else (clones) having the cylinder canted over. Well everything else that has overhead valves I mean.
You’ll have to do some long term testing on that one, give ‘er some abuse because people are always saying they’re rated for residential use and not commercial duty.
