Would it hurt anything to spray carb cleaner into the carbs while the engine is running? I bought this 88 bayliner and the guy last had it running about 2 years ago. Still had a half tank of gas in it. Filled with more fuel. wouldn't run well in the water. idles good but will only run up to about 20mph. sounds like gas not getting to motor. it runs better if press the choke button. Bad gas still? Carbs? Can i take the carbs off and clean them without a kit of some kind? thanks.
