At pretty small speeds, the combination provided by a carburetor is so weak that it'll not ignite correctly, and for its enrichment, at these circumstances, some arrangement during the carburetor is required.

Equally the Hello and Lo screws are simply needle valves. By turning them you enable more or less fuel to movement past the needle. Any time you alter them you're directly managing exactly how much gasoline flows through the idle jet and the key jet.
