I have no idea how you, can swing that piston and rod length around that counter weight unless, you machined down counter weights.
Not the best combination for a 4.375 crank in a 9.800 deck block

Oh the pistons were ever so slightly touching the heads... Inwill post pics when I get home same as his hack grinding on crank I would assume from hitting pistons... I never seen such a cluster fuk build before I wish I would have never bought the scarab to get em!

That there is the reason the rod bearings failed ! The hydrodynamic wedge of oil was lost, you just can't pull a piston, down on top of a counter weight.

Looks like "Goober with the green teeth" assembled yours. That would have to be very noticeable when hand turning that when first put together.
