two days ago, i thought that my prayers had been answered. i bought a sweet little 1982 free spirit that it thought i could have some fun with. alas, i was wrong. although fixing it up with a new pedal & chain and cleaning it up has been fun, i can't get the damn thing to run. i can get it to start very easily, and it will run beautifully for about 5 to 10 seconds, but then it just dies. i cleaned out the carb as best i could with carb cleaner; i'm kind of scared to take it apart, especially if it's unneccessary. i put a brand new spark plug in, and i took the muffler off and cleaned it out too. i tried starting it with the muffler off, and it did the same thing. i also tried taking the air cleaner off and spraying starter fluid in the carb, but that didn't seem to do anything. i'm really at a loss here, and i desperately want to ride this thing to school on tuesday morning. can anyone help me?? thanks!!!
