Spark plug gets gas fouled every cold start

I always check the oil before every mow. OK I will smell the oil for gas. come to think about it the oil doe's appear to be a tad thiner.
this reminds me of the Yamaha outboard engine they have a term called making oil but I think water is being added to oil.

next mow in a couple weeks I'll take a close look down the throttle plate of carb. an report back.
when you say clean are you say to clean cylinder head fins? thanks Slomo

good video you know my cable has been real constrictive the closer to choke I move it. actuely it's never been smooth. this for over 12 years. thanks MParr.

Yes sir. Head and block. All around the engine. Videos below.

I attempted to mow the leaves today. same old stuff fuel is leaking out it's soaked the spark plug wire, an made a puddle on the cylinder head. now I'm concerned w/ an explosion. please advise and thanks

I recommend you remove the ignition coil and clean everything really well with brake cleaner. Once clean, look for signs of cracking in the casting. This is oil creeping from somewhere such as a crack, or casting porosity pinholes.

It may also help to apply shop air pressure through the plug hole with both valves closed.

Clean all of that up and pull the plugs.
Get some pictures of the plugs and post them.
That's a long way for fuel to go and settle on the cooling fins.

I neglected to mention when I turned her over to start battery was at 12.05VDC barely turned her over but I did hear leaking compression. I will clean. when you say shop air into the spark plug hole how much PSI an am I sparying w/ soapy water like a innertube repair? w/ this much fuel all over the engine exspecialy next to the coil thats an explosion waiting to happen correct? thanks Auto Docs

I attemptrd the start up over 24 hours ago so I assume the gasoline on the plug has evaporated? the fuel on the spark plug wire dryed yesterday. strange the cylinder cooling fins are filled w/ gasoline.can I remove the plug now for these images you request?

the previous fuel leaking problem was the exhaust manifold cracked right where it's bolted to the head. remember I swapped the old manifold on which resolved that leak. thanks MParr

The spark plugs will be wet with fuel and fairly clean, if there is that much fuel getting into the cylinders. If that's the case, I'm surprised that you haven't experienced a hydro-lock situation.
I just can't imagine that much fuel on top of the cooling fins coming from inside of the engine. Oil can certainly show up in that area.
I had Kawasaki Mule that would carbon foul the plugs. It eventually got worse. It progressed and hydro-locked the engine. I pulled the plug and cranked it over. Gasoline shot out of the spark plug hole. I changed the carburetor, plug, and traded that nightmare.
