I've got a Craftsman weedeater that I'm trying to get working again. The fuel lines from the tank to the carburetor had dry rotted so I replaced them a few months ago and it wouldn't start so I just put it away and didn't jack with it anymore until now. Today I've pulled the carburetor off of the main part of the weedeater with the fuel lines still attached and pressed the bulb several times and it seems like it just circulates the fuel from the tank to the carb and back to the tank. there wasn't any fuel coming out of the carb itself when I pressed that bulb. I took off the spark plug and it can be replaced so I'm going to do that but it seems like the motor isn't getting any kind of fuel at all. I looked down in the hole where the spark plug is and it was bone dry. I'm thinking maybe the fuel lines are switched up? Anybody got any thoughts?
