I cant for the life of me figure out how to get this plug out. My spark plug socket is too big around to fit in the hole, smaller sockets dont work. Longer sockets are too long and shorter sockets are too short. Also, how do you get the seat off?

 

To get seat off lever is on the right side below side panel, pull lever forward and pull up on front of seat and slide seat forward. For sparkplug 5/8 deep well socket should work fine. I use 2" extension and flex handle rachet to make it easier.
