My XP-360 engine has a 'popping' noise coming from the exhaust when at idle power in flight. Is this a normal sound for my configuration? Or could there be something wrong? Here's my data:
45 hours TT on the XP-360
Airflow Performance fuel injection
Lightspeed Plasma II+ Ignition on top, Slick Mags on the bottom
Vetterman Exhaust
Idle Mixture has a 30-50 RPM rise when mixture pulled to cutoff
Slightly (though noticeably) less noise when running on Lightspeed only
