Remanufactured Carbs

To say all remans are junk is painting with too wide of a brush. I've see good quality rebuilds. I believe the problem comes in when the rebuilder has an assembly line and each particular worker has a basket of say... jets behind him or her, does he or she collaborate with the person installing metering rods??? It is common to find 2 different jets or metering rods in the same reman carb. I have a customer who owns a NAPA/ machine shop around the Canton area. He will not sell remans, due to the return rate. But, I think some quality, mass rebuilders get a bad rap by just being in the business.
