I was wondering if anyone has any experience in replacing the lower motor cover on the Nissan 5hp or equivilent motors. My motor and stand was knocked over and it impacted the side with the upper motor cover lock. It bent the lower motor cover inwards enough to cause the sides of the cover to bow outward. It is damaged enough to prevent the upper motor cover from being locked into place. Does anyone know where I could get a replacement and how hard is it to replace?
