help! i am totally out of ideas here. i've been trying to get my 82 puch free spirit running for the past six weeks now, and i just can't figure out what is wrong with it. i did the tests in fred's guide, and i'm pretty sure it has spark and compression, and --after a new fuel line & petcock-- hopefully fuel. i got a new spark plug, cleaned out the carburetor, cleaned the points, adjusted the carb needle & float......but nothing works!!!! i can get it to start great, and it will run real strong and nice for just a little while, then it just totally bogs down and dies. i'm really frustrated. i feel like i've tried everything, and this is my first-ever moped so i don't have any "moped friends" to help me out. so i am offering $20 to anyone in kalamazoo who can come look at it and tell me what the problem is. seriously. cash. i'm desperate.
