Whats my best carb with little work and good performance?

I had an eddy 800 and it was awful, never could tune it right but i didn't have the metering rods, just jets.

I got my Carters as NOS off ebay, got one no choke 500 and a few weeks later on another seller had one also--unbelievable. Both sold for cheaper than a new eddy carb.

Eddy does have lots of rebuilt warranty exchange carbs for sale. So bad carbs would not surprise me. Almost everything isn't made as good as it once was.
