QFT Brawler; anyone else see this???

I have no idea how that crap got into that carb, but... I can tell you that when I bought mine recently to replace an ancient 4781, I pulled the bowls off, to check jetting more than anything else. It was spotless inside..
I put it on my engine and it runs beautifully. I haven't tuned it yet, due to a brake problem.... but I have faith.. it's already worlds better than the 4781, which I have yet to investigate.
