[grahamd7504]

hi, i have a yamaha f80 (2004) and recently had a carb issue i have now sorted the problem after removing carb,s stripping and blowing them through then re-syncing them, mixture screws are about 2&3/4 to 3 turns out is this about right, motor runs nice at idle
however when going from idle to excellerating it splutters/cough's?? 800 rpm to 5200 runs fine just would be nice to loose the splutter, its about 2000rpm when excellerating??? thanks in advance for your time and experience Graham

for the US market there is no specification.
thats what the manometer and the service manual is for.
without the 4 channel manometer its simply impossible to correctly set up the linkage.
