I have never been happy with the performance of the 7.25E DR power trimmer. Purchased it in 2016 and have only used it a couple dozen times. I purchased an extended warranty after a conversation with DR about how horrible this engine is. Anyway, it sat mostly unused while the extended warranty expired. This motor was bad from the start and has finally died. The current Briggs & Stratton 725 exi has horrible reviews as well.
