RE: YS 120 NC Idle & Regulator Screw Exist?
Dave- I disassembled the barrel & found 3 holes. I believe hole "B" is the air bleed hole you're referring to, am I correct? If so, this hole is less than 1/16" in diameter and I'm a little reluctant to double the size to 1/8". I'm thinking I'll start with 5/64" or 3/32" & check performance. Sound like a good plan?
