I think it is 14mm correct me if I'm wrong...I found an adjustable piston stop from comp cams for 12 bucks and thats new....much cheaper than the BRP unit...what do you guys think?? Item number: 140153202838 on ebay..check it out...may be a cheap way to get a good quality piston stop for our engines. thanks!

I know that I am a little late but I just joined up..A cheaper piston stop tool is a peice of rope stuffed into the combustion chamber.I used that stupid method for years on lawn equipment..
