The shortest distance between two points...

[Terry Bentley]

I had only opened the first pic of your con rod. I did not see the piston you have there. It seems to be an aftermarket stroker piston for the 1.625 crank.

Something else to note: the top of piston is scalloped to open the intake ports sooner.

Below are stock chainsaw pistons. Left is for 1.375" stroke.(Mc5) Right is for 1.5" stroke.(Mc6/10) The skirt is slightly longer for the bigger stroke. Your piston is hugely longer in comparison.
