"I replaced the condenser and points on my Peugeot, but now it runs very ""rough."" When I give it throttle, it tends to die. It just doesn't run like it used to. I'm sure it is not the carburetor adjustment because I had this running beautifully about two weeks ago before the condenser gave out. I'm not sure if the spark plug gap would do this either (can anyone tell me the gap for a 49 cc moped???). I also suspect the timing may be off. I marked the timing and as far as I know, everything is back in its original position. Would a few millimeters advanced or retarded make a difference of this magnitude? Any help is greatly appreciated."
