I have two 660 Holleys with 850 baseplates. A gentleman who is a carb guru told me that my carbs were junk because the choke horn had been cut down to close to the boosters. He said that the air would skirt around the boosters and they would not have perform like they were suppose too. I asked him if that is true why are all the new carbs made the same way? I did not get an answer. So I am asking can these carbs be made to work better with downleg boosters or what is the answer to using them? I tried posting a photo but I can't get it to work.
