kancho23 Posted November 19, 2010 Posted November 19, 2010 Hi Guys I have a 260Z 2+2 (1974) with SU carbies. Engine is stock. I have a couple of K&N filters I am about to install and want to get the most out of the carbies by selecting a needle size on the rich side. Any suggestions? cheers Peter Quote
Riceburner Posted November 19, 2010 Posted November 19, 2010 You can just turn the main mix knob down to richen the mixture and tune to suit. I fitted aftermarket needles to my su's on an L28 with a unifilter, I believe they were SR or SM needles with reworked profile. Quote
