Re: johnson 40 hp carburetor cleaning
You don't need a pic. Remove the carb and take out the four bolts holding the bowl on. Your float is probably stuck. Get a rebuild kit and replace the float, needle valve under the float and the seat that the needle valve sits in. All this can be done with a screwdriver (except carb removal). Set the float (by bending slightly the little "fin" that rests on the needle valve) so it is level with the carb when turned upside down. Make sure that you clean the high speed jet while you are in there. This is the long tube. Blow it out with compressed air or you might shoot a little WD40 or carb cleaner through it. This should get you back on the water in about two hours.
