Hey guys, I posted this in the engine forum as well, so sorry if you see it there as well. I'm putting together a great planes piper cub arf, and am trying to find a spinner nut I can use on the os 70 surpass II 4 stroke engine. The great planes spinner nut threads on fine, but it bottoms out before it cranks down far enough to hold the prop on. Any ideas?

put the washer and prop nut on first, then the spinner nut. This will hold the prop on better.
