Ragleth jet problem

[black cat]

I have a little used Ragleth-40 hours at most-I recently fitted a train department gas regulator..marvellous !controllable gas..Unfortunately after a succesful 20 minute run and after refilling the fire kept blowing out..gas supply was ok..It was a bit windy but nothing that ever bothered it before..the jet had been checked and a coffee filter put in..It was still clear..Wonder if anyone had any ldea about that please..

I know what it is..Having found steam oil in the boiler its obviously haunted!!
