I'm having difficulty starting a Weedeater Featherlite FL20 gas string trimmer. Out of about 40 tries I've managed to get it started a couple of times. Has been this way since I bought it new. The pull cord seems to hang up. Please help. I had a featherlite for about 10 years without any problems except the fuel line broke. Can fuel line be replaced?
