I agree with Hal, this sounds more like a carb problem than a distributer gear. My gut reaction when I read the title of the post was a lean mixture or vacuum leak so that is where I would start for no other reason than you said you just had work done on the carb. On the other hand, I know two guys who have had distributer gear troubles recently so I would not rule it out. Can I cover my bases as well as any politician or what?
