Unblocking a gas jet

 

While preparing my Lady Anne for its second run, I couldn't get the gas to light. There would be the occasional pop when holding a flame over the chimney, but this wasn't followed by the roar of a working burner. 

My guess was a blocked gas jet, and I initially decided to leave well alone. But a few minutes later, something in me persuaded me to have a go at fixing it.  

The working area on Andy's line is pretty good. High enough to be comfortable, and with plenty of space. I had tools in my flight box, so started to poke around with the cheapo spanner set in there. 

To my surprise, I got the jet out pretty easily. The pipe from the tank was disconnected with one spanner (sorry, I forget the size) and then the jet itself was removed. I did turn the tap on for a fraction of a second, to make sure gas was coming out of the tank, and confirm my diagnosis. 

Health & Safety fans look away now, because I cleared it by blasting gas through the tiny hole - basically in the opposite way to the way it would normally flow. In my defence, I was outside, and well clear of running locos. Everything being a bit damp only reduced the chance of a major confligation. 

After a couple of goes, gas was going through properly, so I reassembled the system, and hooray, the loco would light. 

It was at this point I discovered the battery box for the radio control was playing up, so my efforts were wasted, but I'm still pleased. Maybe I'm getting the hang of this steam stuff after all.

Hmm. I was going to steam the Guinness loco this week, but I'm beggining to go off the idea

Go for it. It's a smashing little loco.
