Attached is the blade diagram for correct placement of the deck belt. There is some bleed through from the back page, but you can see the direction of the belt. I have a 1525 mower for the last 11 years, still running and going. Hope this helps!

shaft ha sbrken in steering gear replaceit

its runnig out of gas check fuel filter for being dirty replace it with new one

sounds like a loose ignition wire to me

check the bowl for dirt or try putting in some stable

is yours the newer cub with a kohler command engine? if so pop open the cap on the drain to expose the port.
remove the oil fill cap/ dipstick.
put the rubber hose on the end of drain spout and route it to a safe container.
push in on the spout and rotate counter clockwise and pull outward on it to begin draining the oil.

A defective fuel shutoff solenoid under the carb bowl or a carb that needs cleaning/repaired.

jump start it from your car, the battery is dead
