Any weed-eater guru's out there?

Well replicarracer, you were partially right. I took it apart again and cleaned it up really good, and got a visible layer of varnish off. Still doing the same thing though. I think the carb is the same one in the video Memike posted..it's a walbro. I'm thinking this thing was something like $80 when it was new, and if I take to a shop, it will probably cost more than it's worth. so if I don't get it running soon, I guess I'll have to spend my car part money on a new weedeater.
