Hi, got a 1974 honda Mt125 from my uncle. the ran good for about a week until the clutch cabe broke. After we replaced that it ran really bad. I took off the gas tank and carb to clean them out and it has ran really bad ever since. It gets spark and gas but me and me dad still cant figure what the hell is wrong. It just kind of sputters and runs really sluggish and bad. there is a possablity the there is water thin the gas but i belive most of it was burned out. it often back fires and i just dont no what else to do...I wanna push it off a cliff... Has anyone had this problem before and if so TELL ME WHAT IM DOING WRONG! Any help or suggestion would be much appreciated. Thanks!
