They stopped making the good stuff in the one gallon can a few years ago. I have tried but I can't get the same stuff in a one gallon can. The one gallon can stuff now you can soak a carb for hours and still not get it really clean. If you soak the carb in the good stuff in the 5 gallon can part # 0905 about an hour to hour and fifteen is all you want to soak it because it will start to turn the carb black from the strong chemicals.
i must have got the old. kLR from sitting in a barn and carb was filthy. Looked like new in short order. Not doubting. I must have just been fortunate.
