I worked with the understanding that it is only for already raised land, or at least for land on which something was previously planted . It copes with its task only after twisting the speed, pay attention ! ! There is a screw on the carburetor, it looks just up, it needs to be tightened literally 1/4 turn in order for the speed to grow. It is better to do it together, one presses the gas and the second person tightens the screw. And then at first he somehow slowed down when he met a dense piece of earth, but then everything was in flour. After tuning the engine is very pleased with his work!
