I have rebuilt several rochester carbs.All with varying degrees of success.That is why I chose to get one that is remanufactured.Can only hope that the person who rebuilt the particular carb has more knowledge&experience than what I do-(just going by the vague directions included in kit)when it comes to carburetors.Or you would think that they would know,at least,what/how it should be rebuilt.
Just my 2cents-
