White smoke is usually head gasket, is there oil in the water and vice versa

Petrol - could be crank case pressure build. How is you crank case vent/fliter/breather? could be valve guides leaking oil, rings........ when was last time you changed oil and filter? miles and how long of time( months)?

Ok time to check things then Fuel filter changed, stuck choke, dirty carb/s, plugs, plug wires, carb gasket as you say you see oil there could be sucking to much air and run lean, could burn valves and cause over heating.

So there is the list to check, me would be carb gasket and plugs first and make sure you have proper gap for the plugs.

Also you could start it up let it idle and spray carb cleaner at base of carb where it goes on the intake and see if revs increase if it does bad carb gasket
