273 carb probs!!!

Hmm what size carb is an 1850? Im almost sure that my prob is a carb tuning prob, im not good at it and it is a very precise adjustment that i am just not that experienced in.
Ive been reading all the archive threads on carb tuning and its spinning my head. Ive read about 5 diffrent techniques that i havent tryed yet.
Any one live in the queens/brklyn area that would be willing to lend a hand to a dedicated beginner???
