Okay, tore into the saw tonight, the fuel lines were all brittle and just snapped like a dry noodle.. so i wasn't able to see where they went. as in which one supplies the fuel and which one is the primer line that goes from the tank to the bulb to the carb.
when i press the primer bulb, air shoots out of the top fitting/nipple on it, so i would assume that one goes to the carb.
Also it uses a Walbro carb. I notice the link Star gave me lists it as a Zama carbatrator. They look identical so could i swap the walbro for a Zama?
