Hello Everyone:
Looking for piston rings for my # 10250 model number mower, with a Dura Force engine. Can only find rings with a new piston, my old piston is in perfect condition. Anyone have a source for just the rings.......Thanks in advance

Please note the following from the Toro/Lawn-Boy E engine service manual:

"2. Several piston and ring combinations have been

used. Pistons have been plated and unplated.

Pistons have used two keystone rings and others

used one semi-keystone and one standard ring.

The pistons made for one type of ring will not accept

the other type. However, any piston and ring

assembly can be used in any cylinder."
