Connecting rod "offset"?
People are reading into terms used way too much.
No one has said the the rods control the crank thrust...There are simply way too many experts looking for a window to flex their far superior knowledge or parts show and tell.
The rods have a side that rides,thrusts, touches etc against the rod next to it, flat machined face...call it or term it whatever you want. Start another thread for your recycled rods that go both ways.
