Gas in Oil on Kawasaki Fh430V

I have a good condition exmark WB with a Kawasaki FH430V engine. I try to take great care of my equipment so I check the oil every day before beginning. I notice few days ago that my WB had unusually high oil level and I smelled it. I am almost 100% sure it has fuel in it.

My question, I been told it has to do with the carburetor allowing too much fuel and it is getting into the crankcase? Someone told me to change the float value and float in the carburetor bowl.... Before I start throwing money at it for small parts, I want to see if anyone has ideas on everything it could be. I rather spend little more upfront fixing it right once than throwing small part after small part.... Which usually ends up costing a lot of cursing and money in the end haha.
Thanks in advantage for any help I am given

Somebody already gave you good, cheap (possibly free) advice on what to do.

It is almost certainly a bit of dirt or debris. Try cleaning the needle and seat before replacing it. Or just replace it as a matter of course. Do not run it with gas in the oil!

The most important thing is to change the oil and filter immediately, otherwise you'll slowly but surely ruin a good engine, running engines with fuel-contaminated oil in them will start them to smoking in some order... You do NOT under any circumstances want to run an engine with contaminated oil, not even for a few seconds, every revolution is detrimental.

Granted I've ran some for days like that, but I'm telling you it ruins the engine.

The second most important thing I learned, after changing said oil and filter a NUMBER of times... Is to ALWAYS turn the fuel petcock OFF when the mower is not in use, it's just a habit I developed, right along with turning the key ON / OFF I also turn the fuel ON / OFF.
That alone saves me from experiencing most of these problems.

Now, you might can get away with carefully pulling the float bowl mechanism off the carburetor and clean it out real good with carb cleaner / starting fluid.
