Question about Poulan/Weed Eater No. Te475 952711797 17" Le Gas Trimmer/Edger

1 Answer

I bought a Poulan PPB100 at a yard sale for $20.00. I got it home and got it started and running but it leaked gas like no tomorrow. I took it apart to see what was needed and found that all the fuel lines were crumbling. I cleaned out the tank and cleaned the carb and blew it out with compressed air from a can (computer stuff). I replaced the fuel lines but I'm not sure if I oriented them correctly. There are two lines going through the tank. A very skinny one and a larger one. I connected the new fuel tank pickup to the larger one. I also don't know if I got the primer bulb tubes correct. The string trimmer starts using the normal procedure but it only runs best at half choke. Turning the choke off makes it die. Also if I give it throttle too fast, it'll stall and die. What else can I do? Are the fuel lines and primer tubes the problem?

This is an ongoing issue for users, and rightfully so. Small diameter line out of fuel tank (has filter in-tank on end) connects to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then pushes any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Years ago on 2-stroke trimmers, primers were not even used,...you choked the carb with a slide lever and gravity let fuel enter the carb from above...a few pulls, a "pop"...slide it off of choke and away you went.
If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank.

I just bought a Weed Eater 22" gas push mower. Do I mix oil with the gas to run, as I do not see an oil input? p.s. I purchased this at a yard sale.


If it has a dipstick or plug to check the oil in the engine you do NOT mix gas and oil.
Use regular unleaded gas only and use 30 weight detergent oil in the engine crankcase if it is low.

Lose gas line poulan weed eater


The longest, and sometimes smaller in diameter of the two fuel lines, goes from the carburetor to the bottom of the tank. Leave enough slack in this line so that the filter that attaches to the end will rest comfortably at the bottom of the tank.
The other fuel line goes from the primer bulb to just inside the tank, (about an inch). make sure that you get the right size fuel lines.
(HINT): when feeding the lines through the tank holes, cut the lines at an angle. They will feed much easier into the holes. You can than cut them off square, once you know that you have enough to work with.

Try checking the fuel filter, not sure of the exact location but should not be to hard to find. Try looking in the gas tank if it's not readily located. If small 2 cycle engines sit for any length of time ( 30 days or so) with fuel in them the filters can become clogged. If your not going to use it for extended periods or storing it for the winter make sure you drain the fuel tank and run the carburetor dry.
