Husqvarna WR250 | Motor Breakdown

Due to the stuck crank and the sick smell of mouse piss coming from the motor I decided it was necessary to split the cases to clean and inspect everything. I was happy to find that all the internals appear to be in good condition after a good cleaning. The stuck crank seems to just have been due to dried gas/oil/mouse piss. On the bad side, I found some small gouges in the bottom of the case that need to be welded. The challenge is, the cases are magnesium.

    thats some quality repairs on the magneto/woodruff key. At least the gouges aren’t where the bearing sits.

    yea, i didn’t mention that but included the photos. The stator had fused to the crank. I touched up the crank with a file but because its hardened steel it still needs more work. I need to use my carbide burr with my air tool to get it and the stator cleaned up. Never saw this happen before.
