Hi there, I was wondering if there is anyone who can help with fault on my Clarke 185e. It was actually given to me last year by my uncle, but I am not sure how long he had it. It had a problem when I got it, the torch was staying live and the gas flow was continuous. I had a fiddle with it, put it back together and it was fine, worked as it should do. When I used it last week it started fine but then went back to the old problem (live torch, constant gas) so I had another fiddle with it and now there is no current to the torch and no gas flow. I am thinking that a replacement circuit board might be needed, but what are the chances of finding one at an economical cost?
