I meant if the entire distributor was rotated one way or the other. When I was reinstalling my intake manifold I had the distributor one tooth off, and the only way to even remotely make it run was to rotate the base of the distributor about 20*. If I left the base/cap in its proper location, my truck wouldn't even start, just misfire. I pulled the dist out, turned it one tooth, aligned the base properly and it ran smooth as silk.

If you have the distributor one or two teeth off and the base is aligned properly, the engine can backfire or crossfire..which is rather dangerous.
