Hi Finally after 5 years of rebuilding i've got my GT6 MOT'd :). while it was being tested i asked the tester to check the emissions for me, and the CO2 was over 9%! As i was rebuilding the engine i decided to change the carbs to new SU's, but didnt know what size needles to fit, as its running so rich obviously the ones in it are wrong, does anyone know the correct size/part number please? Many Thanks Andy
