Thanks guys! My issues are a pig rich idle and off idle. I do not have a BJ/BK, etc pair. Just 2 equal 1850s. I have machined the choke housing off, progressive linkage is correct, float levels are right, main jets have been swapped between 60 down to 52. Power valves have been swapped between 4.5 & 6.5. Every combination and the plugs are black in 5 minutes. I am relatively new to carb tuning and learning more than I ever thought I would need to!
I love it, but it's getting frustrating.
