I'm thinking along those lines. I'm about to shorten the piece of wood I'm using to allow more manoeuvrability, and drilling it to ensure I can get it out again! I'm wondering if there's a factory tool for this jobFor me, the biscuit maker was keeping the engine side connection aligned while putting it in place. If you can get it started and gently turn the shaft, it will eventually go on, but getting started is the pain. Might need something you can stick in to manipulate the universal joint once it’s in position so it’s aligned.
