Briggs 4.5 hp engine

My push mower is several years old but is used only a few minutes per week to trim after the riding mower work is completed.
The engine is Briggs 4.5hp, no throttle control, only the stop control handle that also releases the brake when held.
The diaphragm replacement was done a couple of years ago per the YouTube video posted by one of the people here and the results were perfect. Today's problem is with the priming bulb. It quit working and does not work even after being replaced. So a little gas is dribbled into the intake and once started, it runs and cranks well until the next mowing session.
Ideas for fixing this problem?
