In this video, you can see how to remove a 21 PHPG carburettor from a 50cc Minarelli engine. First, place the scooter on a stand for safe working. If you have an open filter, you need to loosen it; to do this, find a screw at the inlet; then insert the screwdriver and unscrew the screw until the filter comes out of its seat. Now you will have the filter and carburettor; next, you need to loosen it from the reed valve. To unscrew it, insert the screwdriver from behind, then pull it. At this point, you will see the pipes attached. To remove the clip from the pipe, hold the carburettor steady and use pliers to detach it and remove the pipe. If you have a broken depressor, be careful as it will empty the petrol tank. Now the carburettor is only attached to the throttle cable. Now that the carburettor is free, unscrew all the screws (for the air and float chamber, etc.). At this point, you can work on the internal components.
