Briggs Stratton 12HP Engine on Noma Tractor: Adjusting RPM, Gas Reaction & Carburetor Issues

Hello
I have a Noma tractor - probably the correct name, but it is equipped with the Briggs and Stratton 12HP engine year 01, from what I know by the symbols on the plate. The problem is that if I want to increase the RPM, I think I'm flooding the carburetor, because the engine goes out, and burns a lot. When I want to increase the turnover I move the lever up, but it works as if the opposite, the turnover instead of increasing decreases, while at the bottom, when the turnover should be slow, they are high. I am not sure if all the strands are fitted as they should be, because someone has already picked this machine. How can I set the RPM so that the tractor reacts correctly to gas?

First, clean and adjust the carburetor and check the spark plug.

Since you say that as the engine increases, the engine floods, check the cleanliness of the air filter. Light without filter and see if there is a change.

Baby candle, just bought. I cleaned the carburetor and blew it away. When I try to fire, I see that it floods the candle (when I unscrew it after such a procedure, it is moist), and moreover, some of the fuel gets into the air filter - I saw how I removed the air filter, that at the bottom in the suction area - it is moist from the fuel. I watched if it was not the fault of the swimmer, but previously when I folded the carburetor wrongly, the fuel flew through the exhaust, and now it is all the time where it should.
If I turn on the turtle, should the first butterfly throttle be closed ??? Because I see that it is not completely. It has holes pierced, so even after closing it should not go out. Currently, there is practically no difference between slower and accelerated revs, and it burns like a small 100/100 tank . I tried to adjust the gas line again, but the effect was negligible.

I was just making the trimmer with identical symptoms and there was a connection between the nozzle and the cylinder, which caught the left air. Check everything again.

In my case, the engine was also flooded, it turned out that the nozzle was eaten, maybe it was with water in the gas tank, today I put on a new gasoline
