I looked at all of the parts diagrams for the Poulan 2150. And they all use the 545081885 Carburetor. So it is the correct one

Gonna answer my own post;
I tore the saw down today, under the coil is a sintered bronze filter that was covered with hardened sawdust. cleaned it up with solvent and a toothbrush. This must be the original design on this machine.

Hello Lou I did not realize there is a bronze filter on that. Great info. You are a RARE breed that can answer your own post. I hope folks appreciate your input; as I do.

Hello Balsterdale,

When it is not idling does it just quit or is it running at a high speed ?

Tony, did you get a response to your question, "How do I replace the fuel pick up in the tank?

John...

I want to know how to replace the fuel filter (Fuel Pick-up Ass'y 530095646}

We have prepared an article and video to help you install the 530095646 Fuel Pick-up Assembly. Even though it may not be the same brand or model of yours. Hopefully it will give the insight you need to replace yours. Here is the link to it.

Your carburetor may need a gasket and diaphragm kit installed. They are cheap and easy to install. This cures some fuel problems, but not all.

It goes on the small line. It takes some effort, but you can use a little WD40 to help get it on.

The fuel system on your chainsaw has a filtered inlet that goes to the input tube of the carburetor. The other hose on the carb is the priming hose. It runs from the carb outlet to the input, or suction side, of the primer bulb. The last line runs from the output side of the primer bulb back to the fuel tank. It is the return line.

When you prime your saw the primer pulls filtered fuel into the carb, to the primer bulb and then returns excess back to the tank. To find the suction side of the primer bulb, attach a piece of fuel line to one side of the primer. Now put the line in a small container of fuel. If you see bubbles when you press the bulb, the hose is hooked to the outlet side of the primer. If it sucks fuel into the bulb then you have found the suction side. Identifying the input and output side of a carb that has a remote priming assembly can be very difficult and there is no rule that applies in every case. Usually you just need to use trial and error on those connections. If you have hooked everything up so you are pulling fuel through the carb, not pushing it into the carb, and your saw won't fire, you should just need to swap the lines on the carb and then it should run fine. The important thing is that you have the priming lines setup to pull fuel through the carb.

I hope this helps!
