Find the idle fuel restriction. With fine/ precission drill bits measure the opening. Then open it 1-2 sizes. Not more that .030 This is the tip in fuel. Not the OV or the main jet, or the accel pump.

On some metering blocks it is visible from the front, others it is covered with a brass plug on top. ( this is a hard to drill version)
