as to why the mixture is too lean...
On a new install: it's the setup of accel pump or metering rods or power valve or main jets or float level or ...?
On an existing setup where this is a new symptom: crud in the carb or malfunctioning accel pump or malfunctioning power valve or malfunctioning fuel pump.
