I've discovered that one of the pinned joints on my crankshaft is loose now (must have become loose when fitting the flywheel) I'll try treating with Loctite 603, but the penetration won't be good so this would be a temporary fix. I don't think I can bash out the pin and re-glue without damaging the parts. Since I have some big sticks of 1144SP kicking around, I'm back to thinking about a turned crankshaft.Simon
