I work at a small engine repair shop and I'm having a bit of a problem with this craftsman weedeater. I've never really worked on one of these types before. It has a carb (of course lol) but theres only one fuel line, and no primer bulb. How does the gas make its way to the carb without something to pull it up the line, nether the less a second line fore the gas from the primer to be pushed back to the gas tank? The person that brought it to me said they found it and just wanted me to get it running, so I don't know much about it. lol. Any help is appreciated! Thanks!

Sears is very good about parts and diagrams. is there a model number. The more info the better.
