For those like methat never haveused the "piston stop".
Could you show us a detail ofthis device?
I guess is a homemade device, is that right?
A sort of spark plug with an electrode removed?

Yes
I use a CM6 plug with a 1/4-20 bolt throught it for 10 mm plugs and a adapter from CM6 to standard plug for standard plug threads, any thing wil work, Just get a bolt that fits the plug threads and put a nut on it and lock the nut in place with some thin CA.
Some people use a wood dowel glued into a spark plug after the <span style="font-family: Arial;"><span style="font-size: small;">electrodes have been removed and drill a hole in the cenetr of the dowel so not to have any compression while rotating the crank
