That looks like a rod hole from here or the rod put a piece of debrie out the front of the crankcase.

I have to agree. It looks as if you have slung a rod.. Or a piece of the rod cap.

Looks like maybe the reeds spit a bearing or something Maybe the bolts for the reeds came undone and got wacked by the crank. It may be fixable

But it runs good :-(
Click to expand...
Stop running it as its only running on 3 cylinders, the crankcase cannot pressurize with that hole so #4 cylinder is getting very little fuel/oil. Hole may have been there from first failure....
