Im gonna do that next, ive pulled the pistons thinking wrist pin brg bad, but they both look good to me, crank brgs both look good, no play up down whatsoever and crank spins nicely. Im taking the cyls and pistons to my machine shop tomm to check piston to cyl diameter and see is bore is by some chance out of round???? If they check out then I guess im putting cyls back on and running it. But yes i do need to take flywheel off and check key. Thank you
