A gx160 generator engine running on HHO gas from a balloon,
this engine was part of a project to convert a small petrol engine to run oh HHO gas as simply as possible, although no very efficient this was a success. The engines idle is controlled by the pressure of the HHO entering the engine, this was controlled by a small ball valve.
