I have a '94 Kgro with a 18 HP Briggs & Stratton engine, I need to take it apart to replace a broken rod. The bolt that holds the pully's on the shaft is that clockwise or counter clockwise to loosen?

I don't think I've ever seen one with the LH threads, but that doesn't mean they don't exist. I usually work with the smaller Briggs.

Hopefully, someone with more experience than I can chime in and be more definitive.

Everyone I have worked on has been standard right hand thread, counter clockwise to unscrew. Use a 1/2" impact gun to loosen.

Most left hand thread nuts/bolts are marked with a notch on the corners of the nut/bolt head. It's not always the case but can be a good clue that you are dealing with LH fasteners.

Same here and great advice. If you are going to use an air impact to reinstall the nut please make sure you thread it on by hand a couple of turns. Seen many engines where the crank was damaged after being cross threaded.

Bill's advise is well worth listening to. Nothing worse than buggered up threads and no tap to repair them with.
