Why am I seeing a sooty buildup on the outside of the combustion chamber part?

Occasionally there are white sparks that come out with the flame. Most likely source is...?
Thanks
The sparks you are seeing is more than likely barrel loading the powder builds up inside the barrel then eventually heats up and comes out the end of the gun or causes your feed lines to burn off (Check your parameters i.e Flows, Barrel Length, feed rate etc) Also check the quality of your Interconnector and Stabilizer make sure everything is still in tolerance
Not sure what you mean by sooty build up on the outside. Inside the combustion chamber you will get Carbon Build up but never seen it on the outside. What I have seen it the combustion chamber becoming discoloured and almost rusting due to poor quality cooling water. Make sure your water is Deionized.
See how you get on with the above
