Thanks grumpy for a very observant diagnosis.
No nothing could have jammed/caught the flywheel except the starter motor. But by design disengages when the engine has started.
My thoughts are I'll get the crank out and get it fixed, replace the flywheel and have another crack.
there was a touch of damage to the keyway before the project started but once there is play I guess it causes timing issues and h a merging and the damage escalates
Anyone else have experience welding repairing a crank?
