The bottom end in the 036 im working on has a slight knock noise when I rotate the crank back and forth slightly by hand. Should I worry about it or let it go? I had the clutch and flywheel off with the cylinder and piston on and im just moving it back and forth barely my hand when I heard this. Its either the wrist pin bearing or the journal bearing but I cant tell which one. It also could be the rod hitting against the crank a little im not sure.
