Here is a very nice original carb for a United gas engine. I believe this will fit a 1-1/2hp to 2-1/2hp engine. The part number is EZV and is 3/4" npt. There are no major wrench marks or wear spots. I believe the needle valve is wrong but very nice. Inside valve works as it should. Please ask any and all questions you may have and look at  all photos. Thanks for looking and happy hunting.
