Okay so I cleaned the air filter (again), changed the spark plug, drained the tank and cleaned the screens and it was still happening, so I handed it over to the local mechanic in Nepal that replaced the battery, rebuilt the starter, tried a new ignition coil from an avenger, cleaned the carb, adjusted the fuel screw, checked the valve timings (with no shims, so using a saw blade and eyeballing it) and fixed some random loose screws and other things - which may have fixed it; but can't be sure yet especially since the rebuilt starter has tight bearings still and every so often needs to be tapped with a screwdriver to get going again
On the upside once it's going it runs a lot better.
