Huge Flamelicker with very special valve

This is an other non runner I bought from ebay.

The beautiful motor was build inspired by the engine "Futura" from Heribert Midderhoff which was published in the german magazine "Maschinen im Modellbau (3/05)".

The main problem was that the fly wheel was to small. (I show the originial fly wheel at the end of the film). So I made a large fly wheel from aluminium and brass.

Another problem was that the spring in the valve was too strong. I replaced it with a shortend spring from a ball pen.

Then the valve was not smooth-running enough. I lubricated it with graphite.

Then I adjusted the valve which was the most challenging part. It has to be tight at the right moment but does not slowdown the engine.
