One method is to turn the starter insert around so that the insert rides on the prop washer and the nut protrudes into the hole in the insert. This method at best works marginally as its difficult to maintain starter alignment during the start, frequently resulting in thrown inserts.

A better and safer method is to use spinner nuts like these: http://www2.towerhobbies.com/cgi-bin...=++&search3=Go They fit your cones perfectly and the are not subject to all the problems of cheap plastic spinners.
