Take the part labelled D: Choke pull-off

Can that be repaired?

My mech says I have to already replaced it since it's not reacting anymore to pressure.

What's the usual price of a replacement unit? Is it a universal fit?

The one in my basic carb aint working anymore. Consequently, I have to manually "idle up" by giving in more gas and air. Fuel economy suffers.

Can anyone give me an idea of the price?

So when I go look for one I could be sure the shop aint overpricing on me.

TIA
