As Ken has stated- when you prime it, gas will leak out of the float bowl, and possibility the air intake of the carburetor . When you let go of the primer it should stop. If you believe it’s not getting fuel because it wont start, it could be flooded. Take out the sparkplug and check to see if its wet. If it is, shake out any fuel. Close the mixture screw all the way. With the sparkplug out, pull the motor over vigorously 12 to 15 times. This may spit out some excess fuel and will add air so the extra fuel can ignite. Put the plug back in. Pull the motor over vigorously another dozen times with the mixture screw still closed. If it takes off and runs for a bit you know that it was flooded.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
