Is there anything special I need to know about adjusting these valves?

Proper valve adjustment is critical to the care and feeding of a 4stroke. I suggest you find a repair manual before attempting the adjustment. If you are experienced at adjusting valves then, you could probably get away with .002 clearance on the intake and .004 on the exhaust.
On the carb, the jet in the bottom is the main jet and is only adjustable by replacing it with a different size jet.
The little jet right next to the main jet is the pilot jet and that is the jet that may be your problem. Remove that jet and clean it. Make sure that you can see daylight through it. Also remove the air adjustment screw on the side of the carb and make sure you can blow air through the passage way. The pilot jet and pilot air system is what controls the idle.
