It's my own fault/I know better than that/nice going, dumbass.
If you look at the photo in the last post, you'll notice that the ignition switch with key is hanging over the top of the newly installed engine. You'll also notice the shop rags placed in the case bores to keep the connecting rods from banging around and to prevent anything from falling down into the crankcase - see where this is going?
The key in the ignition switch made a 25 mile trip on both back roads and the interstate with no hint of falling out. It made the move from the barn to the shop and onto the stand, still no problem with it coming out. Still firmly in place when I wrestled the motor into place and bolted up the oil tank, battery box and the engine bolts. However, less than one minute after removing the shop rags from the holes so I could turn the crank to line up the timing marks prior to checking the end play on the cams, the key fell out, bounced once and made it's way to the bottom of the crankcase. Damn!
So far all my efforts to retrieve it have been in vain. Since the engine is a dry sump, there is very little room around the crank flywheels. But there is enough room for the key to make it's way to the bottom. I've got a couple of more things to try yet before I start taking the engine back out of the frame but I'm not real optimistic. I might be able to shake the key out if I turn the engine upside down - probably have to get another guy to help me do the shaking but I damn sure don't want to have to take the engine apart again.
It's just never easy.
