So far, I have heard some very good things about the daytona single barrel holley 1910 carb. A few bad. But daytona replaced. obviously a 6 only carb. But good to know there is options if need.
also read some good and bad about some 2 barrel carter knock offs.
I tried rebuilding a 1977-era Carter, but I couldn't get the idle passages clear of the 30-year-old gunk. I had to chip it out of the float bowl. Decided it wasn't worth mucking around with, went with instant gratification.
