The old timer who owns the lot where I cut all my wood dropped his Stihl 025 and broke the rear handle. I'd like to help him get it repaired, as he was helping me at the time it happened. I'm looking for the following: 1. Illustrated parts list, showing how this thing comes apart / goes together. 2. Anyone got a rear handle assembly for an 021 / 023 / 025 they'd like to sell? Thanks!
