Craftsman 25 cc Weedwacker

If you go to searsparts.com and put in your model number it will show you a drawing of your weed wacker. Not sure of what you are looking for. Hope this helps.

I need to ask. Did you leave fuel mix in it for a long time? If so then the carburetor will need to be cleaned with a special cleaner. and not the spray can stuff.

There are 2 fuel lines going into the back of the primer bulb. One line goes from the back of the bulb into the fuel tank, and the other goes from the back of the bulb into the carburetor. I believe that the line that goes into the fuel tank has disconnected from the back of the bulb. You will need to remove the bulb, find the line that dropped off of the bulb and into the tank, and reconnect the line to the back of the bulb.

Have you checked the fuel filter and made sure it is not plugged. Make sure the primer bulb is not cracked or leaking pressure. If you have then I would be sure the fuel cap is not bad. To check the cap you should be able to put the cap on the tank pump the primer button to build pressure in the tank and then turn the cap a turn or so and hear the pressure release. If that is all ok then I would think the diaphragm in the carb is bad and the carb needs to be rebuilt.

Clean you needle/ seat inside carb pull apart and clean all out and try it off the w.w. to see if primer works ,also the primer has a check valve internally also make sure that is working, if the primer won;t pull gas through carb it won;t run 2StrokeJim

Sears has replacement parts and so do the OSH stores. If there's no store close, check with a local lawnmower shop and I'm sure they've got lots of replacement parts.

Best Poulan Engine Match (probably real manufacturer):

My decisions are being driven by my experience with Poulan chainsaws. Small hose in tank (long enough to reach all corners), filter on bottom, connects to lowest connection on carburetor. Small hose on upper carburetor connection to small fitting on primer. Large hose from large connection on primer through largest tank hole, roughly mid tank long. nothing on bottom. I suggest you leave the 2 connections on the carburetor long enough they can be swapped (just in case) then try it. if no go swap them.

Typical fuel system and a suggestion or two:

This is how I would configure it if a chainsaw, doubtful they would do something completely different. In defense of Jerry, he knows how it should be done, clarity of instruction could use some help. Good Luck. HTH

Reverse the line connections at the primer bulb. Look carefully, the long port has the line going to the tank, the short port on the bulb will connect with the fuel line to the carb.

Hey jncsurf, I had to buy fuel lines last week. I called the local sears parts store, and gave them the model number. They had a rather generic bag with the correct diameter lines. Just cut to the approximate length.
But now I have a problem: I didn't note which lines went where when I pulled the lines off. Could you tell me where does the line from the primer bulb go: top or bottom barb on the carb? Thanx.
