Would it be bad to store the Honda 15 horizontally for 5 months? Want to put it in the back porch, maybe taking it there in a lil' wagon. I could stand it up once it was there, as I dont have a cart yet. Getting to be too much to take it down and then up the basement stairs. I believe it was shipped to the dealer horizontally. (Was there oil inside motor upon leaving the factory?) Thanks much.
