Stihl chain saw won't start

I have a STIHL MS180 chainsaw that I bought used on craigslist. It was not running when I bought it. The tailpipe was all clogged up with some greasy substance so I wiped it really good and rinsed it with warm water. it starts up and acts like it wants to run , but then it bogs down and dies. anyone have any suggestions on what i should try? I have attached a link to a sound clip of me trying to start it.

Sounds flooded. Try without the exhaust. If it still does the same, reset the mixture screws on the carb.

Ok so I have already tried removing the muffler. It will not start at all without the muffler, and it smells like Gas really bad. Thinking that it might not run without the muffler because it needs the backpressure, I had my wife stick her finger in the exhaust wile I gave it a full choke. still nothing. I will try resetting the screws when I get home today, but I think there has to be something else weird going on.

spark plug was covered in crap and really hard to remove when I pulled it out the first time. so I cleaned it off really good and gently re-inserted it. I'm using brand new gas and the fuel filter seems clean. Even with the freshly cleaned plug,I yanked it until I was red in the face and it just wont run. Pulled the plug back out and its covered in crap again.

Replace the carburetor, sounds like the floats sticking.
It's cheaper to buy the repair kit but there's so many tiny parts to deal with and small orifice's I find it far faster and easier to just change the while thing.

I would start with a new plug gaped correctly,ground the plug to the block and turn it over and see if you get a good spark,if so put a teaspoon of gas into the cylcinder,install the plug and see if it will fire up,I might even dump some misery oil in the cylcinder and turn it over a few times to clear the crap out of it,if there is that much crap in there then that carb needs to be rebuilt also.

If you find a float in that carb, let me know please
Indeed try a new plug and not a used cleaned one.

spark plug was covered in crap and really hard to remove when I pulled it out the first time. so I cleaned it off really good and gently re-inserted it. I'm using brand new gas and the fuel filter seems clean. Even with the freshly cleaned plug,I yanked it until I was red in the face and it just wont run.

What kinda "crap" is the plug covered with?

I should run without the muffler. It's flooded. Are you trying to start it with ful throttle? Give it full throttle and no choke at all and pull it several times and see what you get. Any choking is going to make it worse. If it starts, keep it at full throttle until it clears the crud and smoke.
