If I'm not making a mistake, 168F-2 is a Chinese clone of Honda GX200... but I don't know Generac (not a brand in my country).
All GX engines (and clones) have a decompression mechanism

So 60SPI is perhaps not real - and you engine is good.
You know, It looks just like a small Honda engine. It doesn't say Honda on it anywhere though. I hope that at least makes it easier to get parts if needed.
