I broke the shear pin on my motor a while ago and finally got around to fixing it. Well I found that a nail fit just right so just cut one to the right lenght and it works fine but not sure if that is a good thing to use or not. Its only a 7.5hp Ted Williams. I know the shear pin is supposed to break so you dont mess something up pretty bad so will the nail work ok, will it break when its supposed to or break too easy? thanks for any tips.
