SOURCE: Poulan chainsaw primer bulb replacement

Hello Jay;
The primer listed for your saw and sold by Poulan does not include hoses (do an Internet search for the part number below, there are photos). Hoses are sold separately and are 2 different sizes. You can cap the carburetor to primer connection at the carburetor and your saw will run as all chainsaws did before the addition of the air purge system.

An example of a Poulan "2375LE Gas saw Type 2" follows (may not be your saw):
The IPL (exploded parts list) for your saw is the only detail for fuel line routing and it is sketchy at best; components are listed but may be on different illustrations.
http://www.ordertree.com/modelinfo/PWE/2375LE-Gas-Saw-Type-2/75.2375LE-Gas-Saw-Type-2.1.59.1.html
See the "Engine Assembly" print; item 4; pn 530047213.
Small hose in the tank with a filter on the end (long enough to reach all corners as the saw is moved) the opposite end connects to the carburetor.

A second small hose connects between the second carburetor fitting and the suction side of the primer.
A large hose connects between the pressure side of the primer and fuel tank (return).
I suggest you replace ALL hoses. Do you change tires on at a time?

Plumb the system EXACTLY as the diagram shows. If it will not run you have the 2 connections on the carburetor reversed. It might make sense to leave them long enough to swap until everything is working.
A typical fuel system and a couple of suggestions can be found here:

If your saw is not a Type 2 or an LE (code for Wild Thing) you can find the correct IPL here:

SOURCE: Bar oil leaks into storage case when chainsaw not

The easy fix is to drain the oil tank when not in use. Many saws will leak some oil initially, but should not continue to do so. If it is making a large puddle, oil is getting past the oil pump which may be worn from long use. Make sure the tank vent is not plugged as heat from the engine can increase pressure in the tank thus forcing oil out. Hope this helps!

You may be overfilling the tank somewhat so that expanding fuel (from engine heat) is being pushed out of the vent. Check the fuel filter for plugging and all of the fuel lines for any rot, splitting, or other damage. The primer bulb is supposed to pull fuel from the fuel filter, then through the carburetor and on to the primer which should push the excess back into the tank through another line. If the above does not allow the primer to pump fuel, then dismantle the carburetor, clean with carburetor spray cleaner, and rekit it.

  • The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
  • If the saw is equipped with a primer bulb, the output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill the bulb as it inflates).
  • The pressure side of the primer returns displaced fuel to the tank as it is depressed.

Need to know how to connect the gas lines from the primer bulb to the carburetor on a poulan woodshark model 1950 chainsaw


The lines should be connected to push fuel into the carburetor. The output (overflow) of the carb is routed back into the tank. So, two lines in the tank, one is an overflow (return) and the other is the suction. On the primer one line from the tank and the other to the carb. Connect so as to "push" fuel into the carb when the primer bulb is pushed.
