lloydb, I can not tell much from the sound clip. Is the exhaust header heat shield loose & jingling?
But one can easily check for oil flow to the cylinder head camshaft bearings by loosening the top banjo bolt of the oil pipe, near the fuel valve and carburetor enrichener cable, maybe a 1/4 turn loose. When my engine is started it usually has oil flow to cylinder head in about 5 seconds.
Of course this will not confirm the actual condition of the camshaft bearings from any past sins of the previous owner.
Modify at "YOUR OWN RISK"!
