Not anymore... that was like 30 odd years ago.
fwiw) The combustion chamber was machined to include a labyrinth of cooling channels. The idea was to run the fuel up and around the combustion chamber (counter-flow) before entering the top of the engine in an attempt to keep it cooler.
I pressured it up a couple of times with water and compressed air which made for a pretty impressive spectacle even without flame. Looking back on it if I am to be honest with myself, I guess part of the reason I didn't pursue it further was a sense of self preservation. You look at the quantity and energy of the stuff exiting the business end, then make the intuitive guess of what that would look like as a product of combustion... Some tiger tails are best left un-tugged.
At the time, I was also into building steam engines, so that was my main focus anyway.
