carb question for yamaha outboard

Can someone tell me what this assembly is? It sits on top of my carb on my Yamaha T9.9ELHP and when the motor warms up the pin moves down and the motor chokes.. if I pull it up i'm able to raise the rpm to a stable level and the motor functions normally. I opened it up and the assembly looks fine but I'm no expert and it's clearly not functioning properly; any advice would be appreciated. I'm sure if I take it to the dealer they will tell me I need an entire new assembly $$$
