A buddy of mine has a 024 that recently started running bad (his description) my investigation seems more ot the fact he was playing with the carb setting and got it hopelessy farked. initially with his description i suspected a bad hose, but after I played with the carb a little I managed to get it started but seems like I either get a flat spot out of idle or no upper end power depending upon how i set the carb. anybody know the stock settings for the carb?
