Default Turned engine over by hand CCW by accident

I accidentally turned my engine over counter clockwise very slightly, I was reading some things about how this could throw timing off. Should i worry about this? I was completely not thinking when I tried to loosen the crank pulley bolt, the pulley turned for split second and I stopped. Hopefully I'm over reacting?

Shouldn't cause any problems. It's fine.

Honestly guys, I thought the same thing, then when you look up "turned engine over by hand counter clockwise" in google you get a handful of responses about timing issues, jumped teeth etc lol. I saw that and just figured I'd ask people with actual automotive knowledge, especially with these engines.

It is common practice to rotate the engine in both directions anytime you locate Top Dead Center with a piston stop, as well as when degreeing a camshaft. Won't hurt a thing.

I giggled.

OP, it is okay to ask a legitimate question - even if it seems silly at the time. As you have already figured out don't blindly trust anything Goofle tells you. Now get back to work.

On a simple chain engine like this it's no big deal. It's the DOHC/multi-chain/belt motors that have issues. The tensioners that they use tend to collapse when being spun backwards and then the chain or belt jumps a tooth. But on this simple OHV style there are no issues.
