I have a 77 Puch Newport that was running earlier today. I messed around a bit with the throttle cable and idle screw, then took the top of the carburator out and the whole main slide, choke slide, spring, etc. fell apart completely as soon as I took it out. I put it back together and put it back in several times and couldnt get it to run again. It would sound like it wanted to start when I pedaled really fast and opened the throttle but would never actually kick in and start. It would just die down when I either stopped pedaling or let the throttle go a little. Im pretty new to mopeds so I dont really know what the problem might be. Any help is greatly appreciated. Thanks.
