I went to change the oil in my new Coolster 110cc atv and instead of the drain plug I removed the smaller plug on the opposite side. A spring came out and then a small metal shaft. The shaft has a black plastic cap on one end and I'm not sure which end goes in first . Thanks for any help!

 

You are not the first to make this mistake. Fortunately getting back up and running shouldn't be much of an issue- we answer your question here:
