This is, as far as I can tell, an after market copy of a kohler 26 carb that went on the kt17 engine. It requires rerouting of the choke cable (I changed the throttle cable routing to) because the lever swings the opposite direction but it was fairly easy to do and the engine hasn't run this well as long as I've owned it. If I get a chance I'll post a picture of the new routing I used.
