mate, if you can see straight through the carb without twisting the throttle its stuck on full feckin chat!!!!!!!!!! is this thread a wind up? cratch:
^^ lol thats what im thinking. if you can see that your throttle cable is DEFINATELY fucked no if buts or mabye bruv ur throttle splits in to two... one for the throttle and one for the oil pump behind your variator Get a brand new throttle cable and get it installed by someone who has a clue a shop should do it for under a tenner
air leak? either that or the throttle slide isnt hitting the pin when the throttles released if the slide isnt hitting the pin unlclip the throttle cable and oil cable on the splitter and get back to us
