Start with a compression test and spark test. Report your results back here.

Coils on these are prone to failure the jaring may have damaged a coil.
Pull the flywheel take a look at the coils.If discolored or cracked replace.
You also could look to see if a plug wire has popped loose or been pinched some how.Check for plug wires rubbing.

First do a plug inspection and a spark test. Could be as simple as a fouled plug. Heck, I just replaced both of mine for under $5. Thought the motor was running fine, but didn't know the age of the plugs. Motor runs noticeably better.
