There are #s on the carb body though... K90B. He tells me his says the same. I tried looking on your website, thinking that those #s might be part #s, but both engines use the same part # AX020 for the carb. Any help is appreciated. Thx

Hello.
Please check attached pics-first one is 28 Spec1 and second is 32 Spec1. Please check the case design it is different and it will help you to figure out which motor you have without disassemble it.
