This ad is for an OEM Genuine 1918-1923 Hupmobile 22 Allen Strohmberg H-1 Carburetor Part Number: 553307 This carburetor will come with a dented side as shown in image 2. I posted on the title/description the best I could find about this lovely carburetor. I am sure if that is 100% correct. Please use pictures to confirm form your end. All parts are moving freely. I am not sure what it needs to be working. I am assuming it needs rebuilding or it is for parts only.
