Also, I had seen a link posted here a while back about tuning an engine. Anyone happen to have that handy?

Annndddd... I searched on here, and found that engines run counter clockwise. After a long day of trying to start it, the prop nut came loose. I just wanted to check that I am indeed going the right way. If the threads are right hand, then it runs counter clockwise, and if they are left hand, clockwise, is this correct?

Wow, I have a lot to learn!
