My Generac 66LP (twin cylinder) was barking back thru the carb.
The magnetos (which fire each revolution) were both failing with very weak spark.
They could not fire the spark plugs at the top of the compression stroke.
But they did manage to fire occassionally the next revolution between the exhaust and intake strokes leading to the barking back.
Solution was two new magnetos and it fired right up!
