Briggs bore and 65mm piston?

[Thepartsguy]

I noticed awhile back these 65mm pistons and remembered the 5hp bore is 2.5625 and always wondered if these would fit?

65 mm= 2.559 inch

I was reading 65.088 for for the 2.5625 bore And 66.015 for the piston?

Ok so back to my original thought wouldn’t there be less then a mm between the piston and cylinder?
