Oh yeah, I did not check the crank seal behind that big gear

Case gasket, intake connections, head and base gaskets, crank seals. WD40 is the worst, not seal friendly and can catch fire. A spray bottle with some water works fine, if your engine is warm it just evaporates. If there is a leak the engine just stalls.

Alright, but sadly, did not find any leaks anywhere

Intake to carb connection is a big one most people miss checking. Oring can fall off/out real easy.
