LM-662 Mower: DYMIP60FA 118cc OHV Engine, RUIXING 126 Carburetor Replacement & Considerations

Hello.
A self-propelled mower from a discount with the proudly sounding name LM-662 and another inscription describing the indestructible DYMIP60FA 118cc OHV drive unit. The mower has been working for about 10 hours since the news, but no longer. For this short period of time, I was satisfied with it. There was no problem with starting, it cut nicely, it had a lot of power for this capacity.
I forgot to drain the fuel for the winter and it turned out that the gasket under the carburetor - RUIXING 126 carburetor - dissolved a little. Dissolved rubber from the gasket clogged the carburetor. After cleaning the carburetor, rotation is swayed.
I would like to buy a new carburetor and install it. My question is what to consider when choosing a carburetor?

I bought some Keruidi 107. Looks like the same without a valve and the capacity is also correct. What was installed in the original could not be found. There was one Ruixing 126 but it was for the aggregate and it had a different top.

Another problem arose. Namely, the seals are missing. I figured it is the same bike as the Honda Gx120. There is such a thick gasket on the side of the air filter

On the other hand, there is such a thick plastic (I think it's a carburetor throat, but I can't find a picture anywhere to paste).
I need a diagram of what seals should be there.

Added after 30 [minutes]:

I found a picture of this plastic.
And a photo from the carburetor side

I close the topic. After replacing the carburetor and seals, the mower burns a shot.
