These are sold 2 keys per pack and are .1563/.1573 x 3/4, the are carbon #8 keys. These will
fit the newer style kart cranks used in the West Bend 820's, us 820's, West Bend 610's and the
us 610's. This part is called for on many of these engines but I found it to fit only the newer style
kart cranks.
