Good to know, Webhead. I already bought the carb rebuild kit, so I think I'll do the rebuild, re-use the reed valve with some sealant on the flanges and see how/if it runs. After that (or if the carb rebuild doesn't work out) I'll start stocking up on other 20A spares if you're interested in selling what you have. Like you said, I probably should keep an eye out for a complete spare 20A as well...
