I HATE "primer bulbs"
First thing that comes to mind is the first gas powered push mower in my memory. Unfold and wind a lever. Return fold lever and turn release knob to spin engine. Repeat over and over again. Next step, go get a tool, remove breather, and attempt to pour just a small amount of fuel in carb.
Today.., I push the primer bulb as many times as req'd to get that juicy fluid moving sound. Then the 3 recommended pushes, pull the start rope once, and boldly mow where no mower has gone before. LOL
My grandpa should have had life so good.
2 things contribute to my success, ethanol free fuel and Stabil additive.
