(on Spark Arrestors) Mine is nothing more than a piece of metal screening. I think the theory is that a piece of hot carbon or avulsed metal could fly out the exhaust and start a fire in dry tender. If you use it, be sure to check occasionally to make sure carbon has not stopped it up.

Still do not know if NPS and NFS are the same requirments. Anybody know for sure?

Regardless of where the spark arrestor is located, in the muffler or a screen at the outlet, it needs to be cleaned regularly (if possible). If it is plugged, even partially, it can make the difference between an AC unit starting or not. It can also make the difference of running both the A/C and Microwave at the same time.

As for standards on the Spark Arrestors, the National Forest Service set the "bar" and everyone else follows their lead.
