Doll two-cylinder test runBrethren in steam,
there have been too many wilescos for my taste on the forum recently... 
When I finally managed to get the water-gauge glass sealed (have I mentioned that I bent a new "U" shaped glass from a straight 4mm piece?) and had the boiler already filled with boiling water anayway, I couldn't withstand the temptation. I used the rather small 3-flame-burner of my Doll 364/1 single cylinder. As I have learned (the hot way...) that these burners sometime turn into fire spitting beasts, I remembered a good piece of advice my friend Franz-Josef Stiele-Werdermann (a true GP of steam) once gave me: I added about 5~10% of water to the methylated alcohol - and right, the flame definitely burns far more smoothly (it takes a littel longer to heat the burner up, though).
The engine, I still have not found her in any catalogue I have, mind it is the REAL two-cylinder, not one of those Doll fake two cylinders with one set of valves only, runs really well, enjoy the show. I am sorry for the low quality of the video - I still use my digicam, not a proper video-camera  I have just realized that the mic has not worked properly either - at the end I just try to prove she starts moving on her own as a true two-cylinder
There remains a lot to do: the water tap washer needs replacement, the handles have to be added etc. The smoke rising from the boiler is a cleaning and protection fluid escaping the friendly fire...
When I tried to test the feeder pump I had to realise I re-soldered the feeder pipe lousyly, two needle thin water sprays drenched half of the kitchen. Amazing, what these small pumps can do! (You should have seen the inside of this pump some weeks ago- a rusty mess, the little steel ball inside one of the valves was invisible in this rubbish...). A pity all the paint is gone from the boiler house - but the former owner must have tried to run her on paraffin or wax, everything was covered with a layer of wax which started running as soon as I tried to run her some weeks ago. She must have gone up in flames before... More about this engine later!

Nice engine and a wondeful runner!
BTW I have the "fake" version of this engine.
Two cylinders but only one slide valve

Aw that's a really great engine, what smooth performance at low pressure, it looks very scale when it self starts like that.
Thanks.
