The idle screw only acts on the first stage spring on the rpm weights. So it really only affects the mixture at low rpm.
Please help the MFI community keep the Ultimate MFI resources thread and the Mechanical fuel injection resource index up to date. Send me a PM and I'll add your materials and suggestions.
