Hi Guys, i wonder can one of you help me solve a problem. I have a monument blow torch which i have used, many, many times. However, went to use it today and its badly leaking gas from a hole in the handle. If you look at the pictures, you will firstly see what type of torch it is, secondly you will see there is a hole in the handle which is obviously meant to be there and there gas just pouring out of it. It looks like its threaded but very difficult to see. I wonder would someone with the same torch take a look at the hole in the handle grip and tell me what is supposed to be there???
