I tried to start my slayer today and it seemed like it wasn't sucking fuel into the line. We put fuel in the line ourself and it ran for a couple seconds then stopped and we looked and there was no fuel in the line. please let me know what's wrong with it. thanks

It sounds like you arent getting fuel thru the lines, but this is just a guess.

check for holes or leaks in fuel line, it could be sucking air.
