If the engine is able to recover and the instances of "skip" are decreasing, I'd leave it alone ! I'd be worried I'd let in more air trying to do something, then curing it. A month ago when I ran it dry, and had to purge it all, it took a long time to clear all the air, and eventually long running did the final bits. You may be getting some suction issues and getting air sucked in somewhere, if your fuel is too thick
