my wb1 single carb has started playing up. its feels like it might be starving of fuel? will go as normal then loose power/cough for a few seconds, then take off again. full throttle is good for 5-10 seconds then looses power and splutters, let it idle a few seconds then take off again. it also coughes up and dies when turning sharp and leaning over or hitting a wave. common fault???
help appreciated.
