Ahhh. a previous valve job gone wrong will do just that. The valve seat might have been cut/ground too deep, or the valve may have been ground too far and is too small.
If the adjustment is too far out, a interum solution would be to grind off the end of the valve, called but grinding, (caerfully and accurately square and polished) to gain clearance. (never down to the keeper).
Oil is supplied to the rockers through the mounting hardware remove the entire valve rocker assembly, and (using the book) find the passages and clean them With wires if needed.
The crankcase draft tube on the right side of the engine may be plugged. Take it off and clean it in solvent. (pulsing air at a broken gasket is very normal.
Good luck and let us know the outcome.
