Thanks for the helpful shopping tips, fellows. Incidentally, the gas dripping from my foam air filter seems to be caused by a bad needle and seat. But, I'd like your opinion. Good advice from the forum yesterday enabled me to find out. After I determined the cork float was good (and set right), I reassembled the carb and put it back on. Then I turned on the gas. I left the foam filter and cover off. In about 30 minutes, I could see gas inside the filter housing. Would you guys agree the leak is caused by a bad needle and seat? Thanks.
