Bill, thanks for the info, i hate to take it apart, its like new someone ran it and put it in the basement for a long time, castor and a little rust, bad combo !!! I'm sure its stuck, i have three of these- even a new one- i think i'll put it in the anti-freeze tonight on high, its in the garage it dissolves castor and removes alot of rust !!! If this does not work, its take apart time... Ill let you know what happens.... thanks to all....
