I just switched from a stock stroke dune port motor with stock carbs to a hjr 4mill with 35pwk a/s. Kevin recommended 158 main, 50 pilot, cel needle on middle clip. The main was close I'm at a 155 now, but the pilot and needle seemed rich, I,m down to a 42 pilot and the needle lowered to the last clip which helped alot but I think I may need a different needle, because still to rich, Which needle would be slightly leaner than the cel?
