Older Weedeater / Poulan trimmer purchased at Sears, so the Craftsman # is 358.798420.

Last year I replaced the fuel lines & in-tank filter.  This year the primer bulb pretty much gave up and wouldn't pop back out, so I replaced it.  It pops out OK now, but all it seems to do is move bubbles back & forth.  It never fills with fuel, and consequently it takes quite a few pulls to get this thing started & running.  Once it's going, it's fine.

I really don't quite understand what happens with the primer bulb when things are working the way they should, so I'm not sure what ails it this time.  I'm guessing there's a check valve somewhere, but I thought I'd ask here.

This thing is hardly a premium trimmer, but it sure has held up like one.  I had to put one ignition module in it, and I'm sure it's at least 9 years old.  It gets a serious workout every time I mow, as I have a bunch of chain link to maintain, and this old dog just keeps on working.  I hope to keep it alive another few years.

Thanks in advance.
