Im running an af 185 kit,sterling pipe,22mm jetex 123 main 45/50 pilot,no air leaks,carb set up as sticky's book,petrol mixed 2 jugs to 5 litres,f/f fuel tap,runs well but can I fu*kers like get anything more than a greyish plug colour!! Do i need to upjet or is this possibly trying to hide another problem?? I come from the sooty plug school of thought...Any ideas, cheers Mark.
