I think the advice you reference is interesting, but saying you should only buy a new carburetor I think is in error. Many forum members have professionally rebuilt carburetors which are running fine. The only new carburetors are aftermarket, and I do not think the aftermarket carburetors match the quality of a professionally rebuilt Qjet. From everything I have read, and discussions I have had with many mechanics, Qjets have fuel leakage issues that develop from various places, but they have other advantages. This means they will likely need rebuild every few years, but so will the aftermarket new carbs - for other reasons. In my experience, aftermarket new carbs (Carter, Edelbrock, etc.) have not been trouble free and the quality of machining/matching of the parts were inferior to a stock Qjet. Each to his or her own.
