Well I tried just sliding a new rod on the crank and sort of jiggling it about, it does seem a bit loose in there.. might not serve any purpouse to use that further then?

Yeah, even without the flywheel on if I pull the crankshaft in and out, I can visually see the inner tubular metal part of the bearing moving in and out. Does this mean the bearing is done for?
I have another 21-4C engine which also has this but much less of it, so I was thinking that might be the start of it?
