    I have one of these and used to know the answer, but recently a friend asked me and i drew a blank, they have not been able to reach DW and I bought 3 additional springs when i got mine and pkg is not marked. Does anyone know the factory recoil spring weight on a ECO 45. It also used to be a sticky on the DW Forum, but getting back on there after 4 years I found nothing lol..

    That does sound correct, but I do know the Eco uses a flat spring.. I should of wrote the weight on the package. But, i do believe that sounds right if I now remember correctly.. Thank You...
