Saturday I started adding some more insulation to the garage. Naturally, lots of stuff was moved from normal locations along the walls into a giant mess in the middle. Sunday morning I used the 147 with the blade to clear my drive, the block sidewalk, and neighbor's drive approaches. Only had about an inch of snow, so it was more of a tune-up trial and excuse than anything. I was working my way back home when I heard a real sickening WHOOOMP, and the engine went from around 3000 rpm to 0.00 rpm in a bazillionth of a second. I moved the release lever, pushed it (downhill) the half block home, then pulled it up the drive with the Jeep. I'd checked the oil (good) before starting, and when it popped, I had the blade up, just making the return trip up from the street. It had seemed to be running well. When I turn the pulley over by hand, the crank will rotate about 3/4 of the way in either direction before stopping. Pretty much the same behavior as the K-301 I pulled apart a couple of years ago to find the rod in about 14 pieces. I just hope the block isn't damaged. Right now, it's sitting in front of the garage, waiting for me to get some stuff moved out of the way before I can yank it apart. I have a used engine sitting on a shelf to go in it's place right now, but I'm curious to see the inside of this one. Really don't know why it happened.
