Ignore it, hot pipes igniting small amount of gas vapor in the exhaust probablyOnly recently noticed this but I started hearing a pop or two a few months back upon pulling the power on short final.
I don't recall it happening in the past. I "think" it is that cool pop pop pop backfiring that I hear all the RV pilots doing when they do their overhead break to power off 180 and I hope it sounds cool to people on the ground.
Maybe they hear it and Go "Oh I am going to look up and see what RV is making that cool sound" Then they look up and it is a Comanche and they are even happier because Comanche!
But historically it didn't do it. And now pretty consistently when I pull power on final I hear the a pop or 2.
Backfire on decel is caused by unburned fuel igniting in the exhaust, which would be aggravated by an overly rich mixture. I personally don't enrichen at all unless I'm descending from a high altitude. But I also generally run LOP in cruise as well.
What are you flying? A Bonanza? Presumably something with a constant speed prop. Add power, mixture prop throttle. Reduce power, throttle prop mixture.
Have you tried turning your underwear around?

I wouldn't think so. There is still a positive pressure in the exhaust manifold.Can a leak in the exhaust manifold lead to backfiring when pulling the throttle?
