[QUOTE="SRAD97750, post: 163601, member: 425"] Each circuit in the carburetor (except choke) is vital to the next circuits performance overall. It's like a pyramid, each layer built on the next. Idle circuit is a part of the main circuit... not physically, but systematically. If the idle is too rich, then the needle and main circuits will be 'too rich' as well. (unless incorrectly jetted out) If the idle is too Lean, then everything above idle will be lean. (unless incorrectly jetted out) EX: If the idle circuit produces 10% of the fuel when properly jetted, the needle and main produce 90% of the fuel into the engine. If the idle circuit is too lean (say only producing 8%) then the needle and main circuits will also be 2% lower than they should be. (Unless incorrectly jetted out) Idle is the #1 most important setting on a carburetor. It is the baseline for everything else the carburetor does. (Whether the engine stays running on it's own or not, does not matter) -BIG DAN:thumb: [/QUOTE]
