have eng running fairly well,but just for kicks I pulled the needles just to 
SEE 
what I had.On the base are the letter SC,I know this tell me how lean or rich 
they are,but can someone out there in 6 pot would tell me on scale of 1/ 10 
how rich or lean these needles are.The eng in question is .20 over,mild cam,.70 
off head,header,I have smoothed out intake runs and where carbs mount over 
winter,other than that'Shes a Cherry' and how are needles letter to go leaner 
if 
need be?? Lots of thanks,Bob Arnett Terre Haute IN
