Wazzat?

That would be if the engine is backfiring ;-)


Personally, I simply lean a fixed-pitch prop Lyc to find peak rpm and
have never had any performance or maintenance issues in nearly a decade
of flying. The engine always seems happy and I suspect that at peak
rpm, I'm probably still blowing a significant amount of unburned fuel
out the exhaust pipe. In those planes I've flown that were equipped
with cht guage, the temps never climbed high enough to be worrisome
either.
