My weedeater suffered a blow from falling onto concrete and since then won't start and later I noticed fuel leaking from it. There might be damage from the fall or it might be unburned fuel from trying to start it. I am new to the south Dayton area and don't know any shops that might do repairs. I welcome suggestions for repair or repair shops. How difficult is it to repair those small gas engines? Thanks.

You could have cracked your fuel tank.
