That thing is cool! So that twin cylinder must be a 2 stroke? Those are diaphramed carbs, in fact they look a lot like Mcculloch 101 carbs, if not exact. Maybe it's twin Mac, no idea what models they have. Awesome find, body looks like a 68 camaro in the rear and an 80s model in front from the side profile.

Yeah I missed the kohler part. I'm unaware kohler and Mac had similar carbs but my previous 101s were just like that. Pretty cool.
