1963 Plymouth valiant problem!!!

Why in the holy WORLD would you even THINK about spinning the engine over if you even thought the screw was in the distributor? Sounds to me like you actually want to tear something up. This is simple. Remove the distributor. Tear it SLAM apart if you have to and make sure the screw is not in there.
I don't know anything about cars I don't think it fell in there I was pretty much asking if it did whàt would happen if it was .calm down buddy thanks for your input though. I don't know what all goes on in the distributor I'm trying to learn about cars .
