True that but why do you have to re-set the floats? I do when I rebuild my Edelbeocks and not again. The used 1406 on my 273 has been on basically untouched for 10 years. I don't know how old it was when I bought it. It hasn't been apart for 10+ years. No leaky accelerator pumps, blown out power valves, shrunken metering block or float bowl gaskets.
