Any carb experts want to analyze what I found in my Holley 4150? It was running really rough off idle, around 1500-2500, with some surging if you tried to hold steady speed in 2nd or 3rd gear. This is the vacuum secondary side.
This stuff looked like battery corrosion - very flaky, crusty. I had to scrape it out with a screwdriver and a pick. After the rebuild, smooth as can be.
