One step in troubleshooting in an effort to make your outboard engine work is cleaning the carburetor which is known to get sticky and dirty over time. But how to get to it? This is how:

Step 1: Taking out the air filter

At least on the motor we are working on, which is a 1958 35hp Johnson, the carburetor is buried behind the air filter. After unscrewing and taking out the face of the motor, you will take the air filter out in two steps. First the intake plenum as shown in picture, then after removing the mixture adjustment screws, which are located on the two prongs running through the filter, unscrew and take out the back panel of the plenum. You will now see your carburetor.
