Question about Poulan Garden
I took over a job on replacing a priming bulb. I'm not real sure on how the fuel lines get hooked back up, I've tried different combinations. What am I doing wrong?

This sounds like the carb needs to be adjusted like it is letting to much fuel into the cylinder. There is supposed to be fuel and air mixture in the cylinder to make it fire. If there is to much fuel what will happen is that it will just build up in there and the air wont get hot enough as it compresses to start the engine.

The smaller line is connected to the fuel filter in the tank and goes on the carb body opposite the end with the hole in the cover. A larger diameter line coming out of the tank is the fuel return line and has the little connector on it just inside the tank to hold it in place there
It goes on the carb body (if primer is on carb) by the bulb.
If there is an external bulb...the small line is the same...there would be a larger line going from the carb body (nearest the end with a hole in the cover) to the smaller nipple on the primer bulb. A third larger diameter line would be connected to the larger nipple on the primer bulb and running to the little nylon connector inside the tank. This is the fuel return line and the smaller diameter line is of course the fuel supply line.

Are you sure you have conected the pipes the correct way round, the fuel hose from the tank with the filter on the end goes to the main fuel inlet on the carb, nearest to the alloy pump cover, the other conection off the carb goes to the shorter conection on the back of the primer, the longer pipe on the primer goes back to the tank, just remember the primer pulls fuel from the carb, into the bulb, and back to the tank.

Screw you idle screw in to about 1/2 to 3/4 turn open from seating to the bottom of the threads...spray a little starting fluid into the carburetor and try to crank it again.
Did you use compressed air to blow out all passages in the carburetor? If not then do it, because dirt and debris will plug your air/fuel passages and cause the weedeater not to crank.
If you have to rebuild your carburetor then I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Sometimes the diaphgram may look good, but be a little too stiff to act properly as the fuel pump.
If the machine is over a couple of years old then...I highly recommend that you rebuild your carburetor completly
