Good day ka-tskikots!

I have a Lancer Boxtype model which was a pamana from my grandad and also my first car. It seems may problem sa carburetor which is leaking fuel around the base sa may hole kung saan nakalagay yung throttle ata yun. May repair options pa ba yun or I'll need to buy a replacement carb? If so, where and around how much? Thanks!
