My old HomeLite trimmer had a problem I couldn't fix so I purchased a new trimmer, a TroyBilt, from Lowe's. It actually looked like a scaled down version of the HomeLite. It turns out that TroyBilt bought out the support buisness from HomeLite.
The new TroyBilt wouldn't start. So I called support and spoke with a terribly nasty and incompetent woman. She wanted to know what kind of oil I mixed into the gas. I responded it was the little bottle that was in the box the TroyBilt came in. She didn't know what that was so I asked what did you ship? What's on the parts list? She didn't know and couldn't help me. CLICK.
I throught good money after bad and bought the electric start option. I got the trimmer started. It is so loud that I must buy earmuffs to cut down the sound.
Note: TroyBilt tools are not returnable to the store.
