    1967 300 carb help

    My grandfather gave me an 1967 Buick special with a 300 with a Rochester 2 barrel the carb is not stock and is a reman. Currently I'm experiencing issues when accelerating. I completely cleaned out the carb and noticed it has size 51 Jets in it. They seem small to me. Does anyone know what size they should be?
