It ended up being a filthy air cleaner. It was caked in mud and starving my motor for air. Cleaned it up and all is well. I moved the needle to the second clip from the blunt end. Can running too lean of a needle damage your engine the same way running too lean on the main can? I have ported cylinders, weisco pistons, toomey t5s, +4 timing plate mod, boysen reeds, stock box with no lid and a uni filter. I know that the only way to really tell is to do a plug chop however I just want to see what you guys think about my current carb settings.
