A valid complaint for sure.  These engines will never have idle/midrange like the old 18hps we love.  I attribute this to that darn recirculation system.  Dial in the carb so it idles real smooth, and it will probably have an occasional lean spit or stumble in the midrange.  You usually have to leave them a little rich to alleviate the lean spit.  Needless to say, it is super important that the engine gets up to temp or it wont idle worth a darn.  It is surely fine to alter the cam pick up slightly either way to improve off idle running quality.
