First we need to check the fuel level.
If the petrol is sufficient, the problem may be related to the pollution of the idle governor. The problem can be solved by cleaning the RXX. To do this, you must detach the governor pad while the engine is running and then shut down the engine. Carefully unwind the regulator so that the ring does not fall out. Then, with fluid to wash the carburetor, clean the RXX with the needle down.
You also need to clean the members of the throtting node where the governor is installed. Before you install, you need to lubricate the compaction ring.
