Is anybody using a single prop nut instead of six screws on engines larger than 5 cubic inches (82 cc)? I have a brison 5.8 that I am using only one nut, a 3/8 x 24. It does ok but it slips a little from time to time. The six are a lot more trouble as compared to the single nut, but I like them better. How about you? James Goss
