Had this fantastic bit of British Engineering, kicking around for the last 3 years. Had a go at firing it up last year, my pride got singed as it erupted in a ball of flames. Anyway the weather was not too cold and not too hot, not too bright and not too dark today, so had the balls to see what was wrong. The pipe from the burner to the tank, well, I know what I mean, was about 2mm too long, not bedding down properly. Filed the 2mm off, and got a good fit. Still not quite happy with it, but it works.
