SOURCE: how to replace the fuel primer bulb and fuel lines

I just did a primer bulb not too long ago, but I don't remember what equipment it was on. They are generally easy to replace. First, remove anything that is retaining the bulb assembly, such as cover plate. On my Homelite chainsaw, I simply pried it out with a small screwdriver.
The replacement part itself has two barbed stubs that the two fuel line hoses push onto.
Make sure that you keep the fuel line tubes above the fuel level at all times to prevent leakage.

SOURCE: need diagram of fuel lines

There are 7 different types of the 1950 model (types 1 - 7) and it came with one of these 2 carbs Walbro or Zama. The carbs are different as are the fuel line connections for each one.
Although this video is for the promer bulb you can see the routing of the fuel lines.
http://www.ereplacementparts.com/article/4262/How_to_Replace_a_Primer_Bulb.html

You will have one line from the fuel tank connecting to primer bulb the 2nd line going to the carb. If you connect it backward it does not pump fuel into the carb.

(FYI Types 1 - 5 all have the same fuel line routing.)

Tip

Easy way to install fuel line and primer bulb return line into gas tank


Chainsaw fuel lines enter the gas tank from holes in top of tank. They are sized for a tight fit to prevent leakage. Make it easy on yourself when pushing the line through the tank by cutting a long lengthwise taper cut with razor knife 3 inches or longer to easily feed through that tight hole. Once started you will then have to grab it through the gas cap hole with needle nose pliers, then cut the tapered end flush and add fuel filter. Readjust inside length by pulling from above, then cut to length to upper carb fitting. If connecting to primer bulb a filter is not required and make sure the line goes to fitting on primer bulb marked tank.

You could have a clogged tube from the primer into the carb, but it also sounds like the fuel tank is overfilled.

Fuel line diagram poulan wild thing 40cc


I can't give you an actual diagram but a I can try to explain how it should go. There is a line with the filter in the tank that goes to the bottom of the carb, there is another line from the carb that goes to the in port of the primer bulb, the out side of the primer bulb will go back down into the fuel tank. The primer will pull gas from the tank through the carb into the bulb then return the gas from the bulb to the tank
