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

This the basic plumbing diagram for remote primer. Both the carburetor and fuel may look different on your setup as your would gave either a Walbro WT324 pr a Zama C1Q-W8 carburetor.

Depending on which carb you have, it should be the one on the choke side of the carb, closest to the top.

The fuel line from the tank with the filter on the end goes to the carb inlet, closest to the metering cover usually a chrome cover held with four screws, the other conection on the carb goes to the suction side of the primer bulb, normally the shorter of the two conections, the pressure side of the primer goes back to the tank, this pipe just sits in the tank to act as a return, just remember the primer pulls fuel from the carb, into the bulb, and back to the tank.

Checked all the parts lists, they seem to use the same primer through all types no.s part no. 530047213.

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.

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.)

Thank You for using FixYa.

No drawings or pix, but will try for description--the line from the tank that has the fuel filter is the main fuel source which goes to the upper connection on the carburetor. The lower carburetor connection goes to the intake side of the primer bulb, and the outlet side of the primer goes back into the tank, which has no filter inside the tank. The main problem is determining the correct primer port to connect back to the carburetor. When everything is connected, try priming the carburetor. If fuel fills the bulb, you have everything connected correctly. If nothing happens, try switching the two primer port connections and try to pump fuel again. If still nothing, hook the main supply line from the carburetor over to one of the primer ports and try for fuel again--if still nothing, switch the main supply line to the other primer port and pump again. If still nothing, check for a plugged fuel filter in the tank. If the filter was plugged, then go through the previous procedure again. Make sure to replace the fuel lines with original rubber lines, not plastic. Hope this helps!

If it is a 2375 WildThing find 2375LE Gas Saw Type ?. The last digit of your serial number should be a -1 or -2, the type.

• The filtered hose from the fuel tank connects directly to the carburetor input connection.
• If the saw is equipped with a primer, the output line from the carburetor connects to the suction side of the primer bulb (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill the bulb as the bulb reinflates).
• The pressure side of the primer returns any excess fuel to the tank as it is depressed.

Gas line from primer bulb to carb may be cracked or broken. Check gas lines for damage. If not that then there maybe an overflow problem in side the carb caused by the float shut off not seating correct or worn "o" ring etc.

Replace the fuel filter. Sounds like you have the primer lines hooked up backwards.
