TORO Lawn Mower: Starter Rope Blocked, Fuel Leak near Carburetor, Float Chamber & Gasket Issues

The stuck starter rope problem appeared right after I tried to fix another fault. Well, I noticed a fuel leak near the carburetor / air filter. I took off the filter, unscrewed the float chamber: the float and needle valve looked intact. But that gasket between the filter and carburetor is completely worn out. I screwed everything up, asked another person to start the mower, because I wanted to see exactly where the leak was from - whether from under this gasket or from another place.
Then the starter spun but did not fire the first time, and the second time the line was blocked.
I would like to add that nothing leaked from the cold lawn mower, and before that, even during the leak, the engine ran very evenly, it did not smoke extremely well, etc.

I have a request for help: is this blocking related to some serious failure of the engine / starter, or is it some sort of a question of the mechanism of the cable itself. The mower is quite big, I would have to load it somehow on a trailer and drive kilometers to the site ... that's why I try it myself. Help!

In that case, I'll try to track down and then check the sharpener.

It's not good with checking: I took some plastics from the top and I still can't get to the fan on which the line is threaded. The casing of this fan is riveted to the metal casing of the entire engine or whatever. Does this mean that I would have to take down almost the entire mower to check this unfortunate rope windmill? When I look through the grinds of the casing of this corded windmill, I don't see any obstacle in turning, and I don't see that the cord gets tangled somewhere ... Is there any way to get to this fan and the cord, apart from taking the entire casing off? I would like to add that it will not be that simple either, because one of the top plastics, which I managed to unscrew, has a fuel tank inside and is still connected to the rest of the mower with a wire ... some kind of massacre. So how is it possible to remove the metal casing that is underneath it, turn it upside down and look into the fan? Maybe there are some mary spells that I don't know about? Help!!!

Maybe this engine has adjustable valves, and the work is more serious. I advise you to get a mechanic or take him to a mechanic.

Managed to!!!!
I decided to remove the cylinder housing. I unhooked the fuel hose. The plastic with the fan was visible from the bottom and I could pull the rope without any problems. During the filming, such plastic hooks were elegantly exposed, which are to rotate such a huge contraption all metal. So the cutter turned out to be ok.
But the huge contraption that was to be turned by this cutter was blocked. Well ... I just got it going. I gently turned, the resistance was gone. It doesn't spin slightly, but at least it doesn't lock up. I removed as much dirt as possible. I put it together and IT'S ROTATING !!!

I fixed the primary fuel leakage problem: I replaced the gasket between the filter and the carburetor.

TORO is going like a storm!
Thank you very much for your advice and best regards!

PS. I was spinning the knife before I even decided to demolish it, the knife was spinning flawlessly.
