ok lads....sensible head for a minute. Red, with regards weak diaphrams a little test i did at one point with the carbs off ( i`m sorry) was to get a shortish length of pipe and tape it into the little snorkel thingy on top of the carbs in the middle with some duck / duck tape and gently blow. what i did observe was 3 of the sliders lifted at identical rates suggesting all was fine with those but carb #1 didn`t shift !!!!!!. turned out main needle somehow was jamming / catching down in the emulsion tube. so a quick clean and lube with graphite powder all all was fine. obviously didn`t help me any long term, but maybe something for you to keep in mind for future reference
