[QUOTE="motometal, post: 433008, member: 24727"] No, it's not harmfull as long as it isn't too lean. And if it's too lean, you should be able to tell by how it idles and runs. Right now I use a 25 pilot, air screw about 1.5 turns out, with an S-7 needle jet with the stock needle, 2nd clip notch from the top, with a 410 main. I have also run an S-4 needle jet with needle clip in the middle position. The setup with the S-7 is a bit smoother overall, I think. The stock S-9 needle jet is just too fat. [/QUOTE]
