Many thanks to the members of this group who freely share their knowledge and advice. With your collective help I was able to: remove, clean and reinstall the carburetor; replace the petcock; replace the spark plug; clean the air filter; and change the oil and oil filter. I’ve always been pretty handy, but never considered myself much of a mechanic. The one mistake I made was with the carburetor. When I finished all the work and was ready to throw my leg over for a test ride, my eyes fell to the work bench where, to my dismay was sitting the large spring that that should be under the carburetor cap!! Oh well, that was a valuable lesson learned. At any rate, thanks again to all for your help which you didn't even know you were providing. I think the folks at the motorcycle shop I was taking it to for work will be seeing a lot less of me in the days ahead.

The worst part of rejetting/rebuilding the carb is getting the #%@^$ thing back on! It's super tight!

I hate that feeling when you think you're done and ready to ride and find "leftover" parts!
