I need to know how to replace the belt on an older model Weedeater/Poulan Lawnmower? If anyone can help it would be appreciated.

Any chance of pics or more info to go on?

Model # WE2050

I will try to get some pics. My brother-in-law tried to put the belt on but he said it kept rubbing against metal.

Sorry Bryan but I can't seem to find a weed eater mower on any sites. Try for the pics.
