While you save a few dollars vs buying a brand new one, you also do not get the factory warranty or ability to take it back to local store if something is wrong... In my case the carbs I bought where misrepresented by having keywords that lead me to believe they were the ones that were boost referenced power valves when they were not!!! I was told there would be a 15% restocking fee plus I would have to pay shipping to return them!!!!! I kept them and had to do work to one of the two as floats were not set right but otherwise they were ok for everything except being mis represented in keywords.... I was also told by my local speed shop and e-bay that the refurbished carbs are only available on e-bay and I ordered them thinking I was saving a $100+ for boost reference when they where standard carbs that i could of got new at my local speed shop for a few dollars more and not had to wait for shipping etc....
