After posting the pics to my 122 and 128,
http://onlycubcadets.net/forum/album.php?u=13876, I decided to do the tune-up on the 122 because it was kinda missing and running rough. I got out the box with the new kits, changed the air filter, pulled the plug wire to change the spark plug and....lol, I twisted out the spark plug with my fingers !!! Put the new plug in and yes I tightened it. Started it up and runs like a champ !!!
