It is not recommended to unscrew the screws securing the throttle valves on the axles and remove the dampers unless absolutely necessary, as their displacement can lead to jamming of the dampers in the channels

The brass connecting tubes of the channels pressed into the body should not be removed in order to avoid violating their tight fit.

The carburetor should be disassembled only as a last resort, if flushing and blowing with compressed air without disassembly does not eliminate the sticking of the throttle and air dampers and does not lead to complete cleaning of the jets and channels from deposits.
