The fuel hoses on my Poulan 260 Chain Saw broke up in several pieces inside and outside of the tank. I also purchased a new Walbro WT625 Carburetor for it. and new fuel lines. My problem is that I am not sure I connected the right hose to the right port on the Carburetor.
There are two line Sizes The Smaller diameter line Part Number 530069247 appears to be the Fuel Line. I placed it through the tank wall and installed a new filter on it It also connects to the Primer Bulb Pump and then over to the Carburetor.
One port is on the side of the carburetor with a cover containing 1 Phillips head screw which I think is the Fuel Pump. The other port is on the opposite side with a cover over the diaphragm held by 4 screws which is where I think the larger Tank Purge line Part No. 530069216 connects through the wall of the Fuel tank with no filter to the Carburetor.
I can start the Chain Saw on occasion and it will run for a few seconds. You can not choke it or use the Primer Bulb or it will not start.
