Just freshened up a set of su's and fitted them on a stock 240k with extractors, 2 1/2 exhaust and 240z airbox. Adjusted and sync ed them as best I can and it runs pretty well but a can't get the idle mixture leaner than about 11 without making the rest of the rev range too lean. No markings on the needle but I have measured the stations with verniers to give me an idea of what is happening. 1 and 2 are about .0950 and .0940? Can anyone recommend a needle for me before I buy sw, SL ? Thanks.
