My eight year old 18cc featherlite weed-eater has a carburetor problem. I recently changed the primer bulb and fuel lines but now it refuses to come up to speed. I have adjusted the mixture valve and installed a new spark plug. When I start it, it just barely sputters along regardless of the choke setting. It acts like it is getting way too much fuel. Is there a carburetor rebuild in my future and where does one get the parts for a rebuild.

Many thanks,
