Here is how to replace a primer bulb in small yard equipment. We had an older weed whacker that died so I figured it was time to buy a new one and I ended up buying a poulan pro.
I should have known it was crap when the first one we bought the engine seized the first time we tried starting it.
Luckily I had bought it from the hardware store my dad was working at, so he went and exchanged it for a new one and it worked fine all last summer.
I went to start it this year and the primer bulb was shot, what ever happened to quality? Luckily it’s only a 5 minute job.
Start by removing the air filter and the top cover plate.
The poulan just has tabs that hold it in place, yours might have a screw holding it in.
Remove the fuel lines, while keeping track of which goes where.
I got the replacement bulb off amazon.com for 12 dollars including the shipping, I see they are now cheaper.

Just pop it in.
and reconnect the fuel lines.
Reinstall the cover and the air filter.
You just saved yourself 50 dollars by not having to go to a small engine repair shop.
