Sunl 150 Bog when throttle is pressed

Bogs alot when you press the throttle.. Sometimes it dies. Not really sure whats going on. When i put my hand over the airbox it seems to get a little better...

Usually a sign that it's starving for fuel. Carb jets stopped up,needle and seat sticking,etc. When you block off the back of the carb/air box you're cutting down air allowing more fuel than air mixture in.
