I used one of the China -'chimna' as Sonny says it- carbs for a K181 Kohler 8hp engine..the carb shipped quick from New Jersey and fit right,even came with mount gaskets..I noticed it leaks a lot possibly from an internal passage,it was leaking making a spot on the ground..the bowl gasket leaked as well, I had to tighten it up a good bit but seems to be OK now..small assembly problems I guess..
