There are different ways of setting the carb linkage Al.. At the tops of the carbs where the rod between the two is connected,there should be another setting to attache the bar too. This pushes it up or down depending on what setting its already on..this will stop the cable kinking
i THINK its on the lower setting now or if it isnt its because even with the 2 bars that open the carbs wound right in it didnt work cos they were to long !! if i get chance todayill pop down and have a look ive got someone making me a bit now
