How often to run the engine in a Centurion?

[eddy8men]

they don't like being left outside, the biggest problem i've had with cents is the clutch plates sticking/dragging, i also had this on the cromwell. you can either hold the clutch pedal depressed when stored, which i'm not keen on or make sure it's bone dry before it goes away for the winter. if the clutch does stick a good hose down with a steam cleaner will free it evereytime.
the meteor can be easily turned manaully if you want to avoid running it. on top of the starter motor you'll find a 7/16th hex bar turn it clockwise and this will turn the engine over (slowly)
