Carb tunning ?

[tj455]

I have an 02 superjet w/sizzler pipe , started with b pipe jetting settings- here's what i got. Got low end dialed good, mid seemed ok , tested top end and plug was white-lean. Went 3 turns out-max and still only a little color. Going go from 135 to 140 main on dual 38's to richen top end. This will also richen up midrange right? Should I go more than 140 because it was so lean? Also will this alter the bottom which is good right now?

I'd go with the 140, Yes, it will richen up the mid too, also the bottom a bit

I have an 01 with stock head decked 195 comp sizzler pipe and I ended up going 75 / 140 with 65 gr spring 1.5 n/s and it gave me 30psi on pop and I have my low and hi at 1 turn out. Keep in mind that I suck at tuning carbs! It seems a little sluggish on low end.
