Won't start, fuel flows, replaced spark plug.
Help pls.
Thanks

What is the correct spark plug for this model, and at what gap?

It's not the plug. It's the gear oil on it that's the issue. Blown oil seal?

That would prevent it from starting?

Yes. If it is the seal, it will start eventually but have no power and overheat quickly.
Pressure test is how to confirm. And check that you fixed it. Making and buying pressure testing kits
