I have a Weedeater Featherlite trimmer with an 18 cc engine from 1997. It has no model number posted anywhere on the case, just says Featherlite. I want to know if there were any model numbers for these trimmers, and what they were, since I bought the trimmer used with no manual. Thanks

Hi,
Generally yours would be FL18, though I do not remember that one, I sold the FL17 at Home Depot a couple of years before that.
Manual attached is FL20
Peace,
Clarke
