Moderator DirtyDT Posted September 2, 2011 Moderator Share Posted September 2, 2011 If it runs smooth up to 6k then I would say carb jets or balancing. Link to comment Share on other sites More sharing options...
KirriePete Posted September 2, 2011 Share Posted September 2, 2011 Definitely sounds like your main jets are the likely problem as this is where they start working properly. So a strip and clean is in order I would think - you might get away with blasting aerosol carb cleaner up from the float chamber if you don't fancy a full strip-down, certainly worth a try.
