Well, the PO certainly was not a stickler for details. Sure looks like there should be a big water leak at the top of the head with the thermo head gasket installed. Oh well, the head has to come off for the head gasket anyway, so I’m sure you will find a creative way to reattach the broken cover mounting.
OK, you say the engine sneezes lean, but adjusting the needle makes it too rich. I suppose it could be possible that there is a problem with the pressure tank/lines/intake manifold causing a lean condition… Perhaps this condition caused the crankcase leak due to excess backfire/sneezing.
