We attacjed our cylider with our normal gas stove before 3-4 days and used normally as alwayd. And now currently its not working properly. And also when we try to spray some gas out from it using pin after removing regulator... It also don't throw any gas out of it. So now our cylinder is about full but it it not throw any gas out of it hence we can't light fire from it.
