In both singles and twins, I've called off a flight when during the before-start checks I found the fuel selector could not be placed in the OFF position or that safety catches meant to prevent inadvertent movement of the control to OFF had corroded (from lack of exercise) to the point they would not permit selector movement.
The rest of the aircrew completed their before-start checks while the pilots filed and got the weather brief.
