What do sparks mean?

Thanks for the answers. Like I mentioned in the first post, I was running at a pretty high RPM. I guess these sparks were just parts of the muffler flaking off and coming out.

It sounds like this isn't anything to really worry about, but I might want to start planning for a new exhaust stack. That makes the most sense. I'm starting to see a little rust on the bottom of the stack where it comes out of the tractor. It would stand to reason that the inside doesn't look much better.

If what you're doing isn't working, do something different

IPF, that simple yet profound signature of yours just hit me like a ton of bricks. Hadn't noticed it before. By god, that's just what I'm going to do - thanks!
