Honestly youll proably have the best luck with the grungiest greasest carb you can find, because that means it ran the longest. As long as the carb is not oxides horribly the looks dont matter.

DONT BUY THAT CARB, you will be frustrated with it unless your just collecting it for parts.

what does matter is NO POLLUTION EQUIPMENT. The less extra plumbing the less fits you will have making it work right. If you have to and you are serious about the TQ pay the extra 25-50 for a none pollution carb. Im sure someone will sell you one if nothing else.

Hell, Im heading up to Iola, WI swap meet tomorrow, Ill look for one for you.
