I need a secound opinion on my jetting. I have 12.5:1 416 piston, stage 2 hot cam, mild porting to head, stock size valves, sparks full exhaust 2" core, white bros cdi, k&n filter w/ outerwares and no lid. Before I started working crazy overtime I started to jet my carb but, I was using 114 octane leaded fuel which I quickly found burns gray not black so I never got the color I wanted on my plug. I am now to rich and need to run out some of the race gas and add 93 so I can get some color on my plug. What would you say whould be a good jet to start with?
