I have an HS Pony gun that I would like to modify(same as the HF and Caswell). The problem I have is that the gun tends to spit powder frequently. I’m wondering if this is due to the cup top mount position. What I would like to try is to move the cup to the bottom and see if this doesn’t improve performance.
Has anyone disassembled this gun? Are there any issues with the wiring, etc. Here is a picture of the original gun and cup position and how I would like to make it.
