Well, it appears that the problem is licked!!! I installed a new air filter, and it ran smoothly at all speeds with no black smoke. I’m guessing that the fibers in the paper element in the old air filter had gotten wet, causing the engine to “suffocate”, so to speak. Although I can’t prove it, I...

Yep, I already mentioned in my previous post that I also drained the carburetor.

I just pulled the dipstick to smell the oil, and cannot detect any obvious gas smell in the oil. That was my first suspicion when I got the mower home three weeks ago. I’ve changed the oil since then, and the oil level is still dead on the “full” mark on the dipstick when I checked it just now...

In my previous post, I mentioned that the engine started and ran flawlessly, at all speeds, but failed to mention that was with the air filter OFF. Even after reinstalling the tube insert and breather tube, it ran flawlessly, at all speeds. However, when I reinstalled the air filter, the black...

Here is the exploded view of the carburetor on this engine, to let all of you know what I have. It is a different carb than the one posted above in the link. Thanks for the posts, guys!

Thank you for the tips, 1fixitman! Your suggestions make a lot of sense, however, the carb is currently still on the tractor, and I'm on vacation starting tomorrow morning, and won't be able to pull the carb to see about the o-ring and plastic piece until I get back. I did print out an exploded...
