Remanufactured Carbs

I have been in the Automotive business since I was 16. I have rebuilt carbs all my working life. When I had a problem, which rarely happened, it was my fault. If I need parts, I scavenged them from cores. I have only bought four new carbs in my seventy nine years. Two of them were Edelbrock copies of Carter four barrels. Another one was a Holley spread bore. The last one was a Chinese copy of a Carter two barrel, which I had to rebuild and is on my '65 Barracuda .
