If the engine is out of valve time, then engine would not run at all, not just run bad. Off one tooth will make it pop and backfire through carb or exhaust. It sounds as though the engine needs a good tuneup, clean carb, points, condensor, cap, rotor, plugs, plug wires, etc. How did you determine the valves were advanced 20 degrees???
The best way to tell if the valves are in time is to take off valve cover, get piston to top dead center on compression stroke and then both valves should closed. If you moved on way one valve should rock open and the other way it should rock open the other way. Hopes this helps you a little, but before you go diggin past the problem looking for something else, look at the simple things first.
