A3 Valve/Regulator Drive problem

Dear everybody,

I'm the owner of A3 Flying Scotsman leave steam (used) and faced the following issue. The Regulator Drive Rod has been somehow broken and "fixed" by soldering (see pictures).

Now the regulator seems working, servo and gears rotating, even the drive rod moving. But the steam valve not working, no steam flow and, of course, no train movement. Control LEDs at certain switch from green to red, then both light at the same time, which I also think is abnormal.

I would be grateful for any ideas on how to fix this.

Probably the right way is to buy the new Regulator Drive Rod, which is available from the shop, and replace the broken one.

But I don't know, how to disassembe the train to have access to drive rod and valve. Are there any instructions available?

Thank you in advance, Dmitry

In the video I can´t see or hear any sign of steam generation. Did you wait until you get a "hiss" from the safety valve? Please forgive me if the question is silly.
