Prestart engine lube....does this work?

Best way to do that would be to just remove all spark plugs. This way the engine will almost free-wheel with the starter. Just pulling the coil wire by itself will still allow compression to build in the cylinders.

Without a doubt, the Accusump is the best way of handling a dry start. However, if one is not available and it's been a couple of weeks since the engine has been started, then I would use the method above. Keep in mind that a bearing will probably never be absolutely dry with oil. I've torn down engines that have been sitting for years and the crank journals/bearings still have oil on them.
