What brand and size engine is this?

[KarterJ1]

New to me go kart. While trying to clean it up, stupid me broke the rocker arm stud and now I need to figure out which engine this is so I can buy a replacement part.

If you know a source for the rocker arm stud, please share!

Hint: the fuel tanks says “Predator”. Could it be a much older and smaller Harbor Freight Predator?

Isn't the Harbor Freight predator just the name of the whole line of small gas engines? I thought they made them in all the common sizes? 3-5-6.5-10-13 HP

Hello? I suppose everyone is on holiday break! After all the egg nog, maybe these markings might help?

Answered my own question. Based on the marking “152F3” it appears to be a 3hp 97cc Lifan engine. Looks like an older generation of this...https://www.homedepot.com/p/LIFAN-5-...F-3Q/203281925
