I replaced my fuel line on my Craftsman blower and now it won't start. If I pour fuel into the carb it starts till that runs out. What's up?

Check and make sure you didn't pinch the line ,
Is there more than one line , if so make sure you didn't cross lines
Check the fuel filter in the tank.
Luck

Was there a clunker fuel filter on the end of the line inside the tank, did you reinstall it?
