Keeps running but won't start when pulling the cord.

Oops, looks like someone beat me to that. Regardless the point is you should also check on your air vane and thermal arm now to make sure they're working too. One thing you could try is to manually operate these linkages to see if you can get it to start. Do so with caution of course. Hold the choke closed and rig/tape the throttle open about 1/3 of the way and see if you can get it to start, then let off the choke slowly.
