Mower won't Start

Mower won't Start
Ok, guys...go easy on me, as I know little about these things.
Unfortunately, I hit a root with my Craftsman 6.75 Horsepower 22-inch lawnmower (Briggs and Stratton). The blade was bent, so I replaced it.
Then the mower wouldn't restart. I replaced the air filter and the sparkplug, but it still won't start. I can see that when I try to restart it, the blade seems to turn fine, so I'm assuming that there wasn't more damage underneath somewhere from hitting the root.
When I try to restart, there is at times a little black smoke from the muffler and at times the cord doesn't pull entirely smoothly (although it usually does).
Any ideas? Please?
TIA
P.S. Just now, when I tried to start it again, a little white smoke came out of the muffler.

If the engine stopped abruptly, there may be a shear disc or pin on the crank shaft that may have been distorted but didn't shear off completely throwing off the timing. If the timing's off by enough, it'll be almost impossible for it to start. I recommend getting a manual for your machine and see if there's any shear discs or pins you can check for distortion.
Let us know what you find.

Yes, it sounds like you have a sheared flywheel key. Remove the engine shroud and the flywheel nut and have a look. You'll need a puller to remove the flywheel.

This is exactly what I found out tonight, after taking it apart. I appreciate the advice!

Ok, I wonder if I could get one more bit of help?
Now that I have a little time to devote to it, I wonder if anyone could tell me if the flywheel key for a Briggs and Stratton engine model number 125k020500e1 is aluminum? Can I buy one of these anywhere? Or should I just order it through the site online?
Thanks!
