On a case that has not been line bored, it would be highly improbable that the bore would be put of align. I assemble to point of having the rods dangling out the sides, flywheel on, and rotate the crank assembly keeping my hand on the flywheel so I can feel if there is anything binding and not letting it rotate freely. If you feel the slightest bit of bind, then you take it back apart and check for shiny spots on the bearings. _____ From: tcb-bounce@xxxxxxxxxxxxx [mailto:tcb-bounce@xxxxxxxxxxxxx] On Behalf Of Mark Sawyer Sent: Tuesday, March 28, 2006 9:13 AM To: tcb@xxxxxxxxxxxxx Subject: [tcb] Re: Ronnie's engine 1.9 liter type 1 in a 71 type 2 Sammie Smith <slsmith@xxxxxxxxx> wrote: Which engine does he have?
