Do small engines run clockwise?

All small engines turn counter clockwise, looking at the shaft end.

What happens if you turn a motor backwards?

When a motor is turned backwards, the timing relationship between the crank (timing mark) and the cam (distributor, etc) changes, so parts can be installed out of time, etc. You can turn it backwards, then just need to turn it back forwards enough to remove the slack, restore the timing relationship.

How do you tell if a motor is CW or CCW?

You can determine shaft end perspective by simply holding your motor up in front of you and pointing the shaft at you. If the shaft is pointing at you and rotates to the right, your motor is clockwise shaft end, or CWSE. If the shaft rotates to the left, your motor is counterclockwise shaft end, or CCWSE.

What happens if you turn the crankshaft the wrong way?

The problem with turning the crank backwards is the risk of the timing belt jumping a tooth as the tight side of the belt is relaxed and the slack side tightened. Even if the belt does slip it will do no permanent damage, but you would have to resinstall the timing belt as per the garage instructions.
