    Stihl MS 311 engine swap

    chainsaws repaired

    A pair of customer saws in yesterday. The Stihl 880 was reassembled with a new oil pump drive spring and test cut. The Echo 280e was a no start diagnosis, repair and test cut. It needs a little more attention but is repairable. Talk about one extreme to the other.

    I found the answer
