1) the 2 pistons are different, one is sealed and one isn't. The sealed one goes on the cold cylinder.2) The pistons fit flush with the end don't push them in too far.3) It won't run with a small flame it needs a lot of heat.4) The heat tube is adjustable don't push it in too far.

This is a good thing for teaching. Looks great with the polished brass. Easy to assemble. I couldn't get it to work at first but realised the small piston was letting air through. I had some blue tack to hand and put a bit in the small piston end . Making sure not to put any on the glass cylinder . Now when rotating the flywheel there is pressure to Both pistons . Now it works really well.

It simply doesn't work and the instructions are not clear at all, thank god for you tube

I asked for one of these for Christmas and whilst I eventually got it working, it's not that great.Firstly the coating is very poor, full of ripples, lumps and bumps and marks. It looks cheap.Secondly the kit was mostly assembled, little left for me to do - apart from adjusting, sanding, piling, etc, to get it to run. The badly translated and incomplete instructions didn't help.I use methylated spirit to run it and that works well and eventually got it lighting a small string of LED's.For the money it's OK, but if you want something to display, then no, it looks pretty bad.

Il faut être un peu bricoleur main une fois montée elle fonctionne très bien

Hace lo que se supone que debe hacer una vez montado. El montaje tampoco es especialmente complicado, casi todo viene ya hecho.

Wir hatten sehr viel Spaß beim basteln. Für jeden der sich für solche Dinge interessiert ein lehrreiches Spielzeug. Kaufempfehlung.

Si bellissimo ma occhio xchè ci vuol l'alcool a 95° se no non va nulla.
