Well, I was bragging on how smooth my motor was running and a week or so back suddenly it started running a little rough. I had to speed the idle up some, messed with the mixture screw, but couldn't get it like it was. It is not a solid miss and doesn't seem to miss at higher RPM but it is kind of an intermittent miss. My first thought was something got in something in the carb, but could it be points as well? Points is one thing I did not replace so I wouldn't mind throwing a new set at it anyway.
