Dirt settles also in the vacuum tank and in the main gas tank. These should be drained until the gasoline comes out clean. It's not much, but the little left there might clog up the fuel feed line and check the whole supply system.
Even with these drained clean, the feed line should be blown out Particles of greasy dirt passing through the line might stick to the sides and, after collecting one on another, might cause the whole line to be stopped up.
The carburetor, too, should be drained clean the same way, and the needle and valve washed out with kerosene.
