Turn the idle screw up ?

Try just turning the idle screw up a little? Idle speed is 700-750 rpm. Does it start Ok if you just move the throttle lever up a quarter inch or so? (in neutral...). If you have the YDS software or jumper wire kit you can check the Throttle Position Sensor setting as well. Should be about .60v - .65v at idle.

Adjust the idle screw when motor is warmed up...

Yes, adjust the idle screw when the motor is warmed up.
