I would like to try to take the carb off to clean and adjust it, but I haven't attempted it yet. Are there any on-line videos or instructional information on how to first take it off and how to clean and adjust it after it is off? I've installed the starter and solinoid and replaced the water pump and I hope I can do this but I don't know how to adjust the carb once its off and cleaned. Or should this be left to a professional?
