if you havent messed with it it's prob ok.
Fred, thanks although not entirely sure I understand all of it
! The only things I have tweaked are the mixture screws, the idle screw and the throttle stop screw as this was adjusted so that the carbs won't opening fully...I now have an extra 200rpm at WOT
I'll screw the mixture screws back to 1.5ish turns out, and clean the spark plugs (whats the best way to do this?).
Scary, sounds like a plan, thanks. I'll see what effect adjusting the screws has.
Any more help appreciated.
