I already do that cobra. I think my main problem is that when fuel gets on the bolt, it loosens up right away. I've bought another bolt ( for 3 bucks at Hobytown USA

), but it still does the same thing. I have a 4-way wrench, but for some reason, it doesnt fit around the prop nut, so i have just been using some pliars to get her on there tight. Before when i had this problem, i took the spinner off, and just started the engine by putting the starter on the prop and spinning it that way. It worked, but the guys at my club said i should use a spinner.
A question about the Dome nuts: Do you rest the starter on those? Wouldnt that just unscrew it? Hobbytown has them for 15$, so i dont want to get one and then have the same dumb problems.
Oh, by the way, i hate Hobbytown.
