Just my opinion that converting a glow engine to diesel may not work as well as one would like. The higher compression ratio of the diesel creates much more stress on the connecting rods and wrist pin. I converted a K&B Sportster .28 to diesel operation. The power increase was not as significant as I expected and in fairly short order, the diesel operation beat up the cheap non-bushed connecting rod ends. Pick the glow engine carefully for a very robust rod and crank. Also glow engines ported for very high rpm don't always do as well when converted to diesel.. In my experience, it is usually better to just buy a good quality diesel to start with rather than try to convert a glow engine.
