I can't get my quad to turn over, which side can I use a socket to manually turn this THING over just to make sure it's not stuck. My new startor did nothing.

 

Welcome to the forum Daryl40!

The left side of the engine just in front of the sprocket. Pull off the cover and the flywheel is under it.. You should be able to turn the engine over by hand.. if not pull the spark plug.. if you cant turn it then its locked up.
