You're running on too lean AFR. Get it retuned to normal, otherwise fry your valves.

Rich mix doesn't fry valves. Neither does it cause backfires. Its caused by either lean mix or by faulty spark plugs.

Sometimes RICH mixture does causes afterfires (exceptional cases). But, here I think, you're right. He is running too lean.

I second that very rich mixture can cause that.

MY Fuel injected 220 had this problem initially. All i did was fueled up at a good buck from then on.Once in a while when it misfired, i remove the spark plugs, clean it with a cloth, install back.I had no more mis fires.
