    Dude the 2nd stage jet is a non removable jet and needs enlarging to allow for fueling if increased boost, do you have a wideband afr kit installed??

    Re: jetting aa carb

    thanks for that, im currently runnin engine in, not goin over 3.5k revs, the only thing told to look for is 13.5-14.5 on tickover, this carb is supposed to be totally standard, iv got tag cgb wrote on statin jets (think), this one seems to run abit weeker on afr, but I mite be overlooking the old one, does the jets have size number on them?. suppose rolling road would be the easiest way. iv got my boost gauge (aftermarket) pipe coming off the hose between carb and aei, is that right,

    If you need any help with the carb simon, send me a pm or give me a call. I can probably call over to yours if you get stuck too
