quick check list:
flat bulb = restriction before the primer bulb
bulb not flat but can pump alot of fuel into motor = fuel pump not operating properly.
this is the quickest and easiest way to test.
go to your local sears etc buy a el cheapo vaccum/pressure guage and tie it into the line before the bulb. vaccum should not be higher then 4 inches of mercury if i remember correctly.
p.s. two most common problems with fuel system check valve on fuel pick up on tank doesnt work or is stuck and fuel pump is out. hopefully you do not need to change the fuel pump.
