I had to replace the spark plug and the coil to get my moped running, and she was going great for several days, then the throttle would stop making it go and it would coast to a stop and shutdown completely. I also had great troubles trying to get it to idle, and never really fixed that either. The carburator is clean and seems working right, the gas is the right mixture according to the instructions on the bike, it's getting gas besides a slight leak, and the muffler doesn't seem to be clogged. I've tried different spark plugs thinking it's getting too hot, but I'm not even sure what type is crossreferrenced to my garelli. I don't understand why it won't go more than a block or two now without boggin out, when she was doing fine a short while ago.
Can anyone help me?
