Hi Gadge, The motor runs alright but blows a fair bit of smoke. That is probably my fault for tipping the mower up too far trying to look underneath it. That might burn off after a while?
Yep, that's it. Tilting it will have made the sump oil flow into the valve spring chamber and its breather valve, which is vented through the carby throat. If you take off the air cleaner, I'd bet there's oil visible in the carby. It will make its way out eventually; just run the engine until the smoke clears!
It also seems to be weeping oil around the sump seal.
Do you mean the crankshaft seal, or the crankcase cover gasket? If the clutch body is loose on the crankshaft, the resulting vibration can make the seal leak, and is probably the cause of your grass deflector screws coming loose too. It could also have broken the seal between the gasket and the metal sealing surfaces.
The torque setting for the crankcase cover bolts is 85
in-lbs, for this series engine.
