Usually this (back-fire/after-fire) happens because of a dirty carburetor, or bad gas. Gas can go bad with age or it can be bad because of water from condensate. I'm not familiar with this particular engine, but if it more than 1 spark plug, a fouled-out plug can also be the culprit. If you clean your carburetor, I suggest just using a bit of gas to soak it and brush it etc. That carburetor cleaner is rough stuff and it will burn you badly. I don't use it unless I've got a stubborn one. Hope this helps.

Brand new gx390 Black Max generator backfires when shut down. Might this be plug gap problem?

If you can access throttle linkage to the carburetor, slow the engine speed to idle before turning off. As mentioned in the previous answer ... turning off the fuel valve and letting it run dry is good if you are not planning to use it real soon.
