Thank you everyone who replied. There was black oily gunk EVERYWHERE and it took me quite a few hours just to clean it all. I watched the video Crow Bar posted a link to and realized parts were missing, so I called the guy who initially began to fix it, he had the air filter holder in his tool box and returned it and a few other parts.
Had I been the one to take it apart I would have known how to put it back together. Anyway, this was my first small engine carburetor replacement and it was easier to do than I had anticipated. The chainsaw runs beautifully and I am kind of proud of this accomplishment.
I will now turn my attention to the trimmers and then my Troy Built Tiller. Growing up, Used to help Dad repair car engines and once helped do an overhaul. Never knew that small engines could be so rewarding to work on.
Have a great evening.
