Here are some alternatives..
From the Cushman manual....
What Spark Plug should I use? Most references state that a Champion #7 spark plug was used for 1948 and earlier scooters. However, the Cushman manual for the model 32 and 34 published in 1943 states that the correct plug is a Champion 6M. A suitable substitute for either is the Champion D-16 and this is also the correct plug for all later engines that do not have a tapered seat. Heads with tapered seats used a Champion F14Y, which is no longer made but some Cushman dealers may still have a few in stock. A Champion RF14Y or RF14YC is an acceptable substitute and is readily available, but it is a resistor plug. Other plugs often recommended for the tapered seat head are the Bosch 6200, Champion 4011, NGK WR5, Champion 870 and Autolite 46. You should make your own determination as to the suitability of any of these alternate plugs. Be sure not to put a tapered seat plug in your non-tapered seat head or it will likely be ruined. I gap all plugs at .026. Cushman gave various recommendations for gaps over the years, .027 to .030 for the 6M, .030 to .033 for the #7, and .026 for the F14Y. If you have excessive fouling problems you can go to a higher heat range plug. A higher number plug is hotter and a lower number is colder. Many of the hopped up engines work best with a colder plug.
