Well after having my weekend onboard rudely cut short by heating failure, I removed it and brought it home for a good dose of looking at! After stripping it down I have to say, I'm amazed the bloody thing ran at all The burner was so choked up with carbon, that the glow pin was barely visible. Anyhoo, I've decoked it and got it back together without having any bits left over......Result! Now I have to wait till my next boaty visit to see if it actually works
