Hello 12'ers
I recently had my carbs balanced which has made a huge difference to performance. However when pulling the power on landing my Idle speed is now 1900-2000 rpm.
What should it be? what is your idle speed with throttle closed?
Thanks a bunch

The challenge I face on every landing is getting the altitude and airspeed nailed on final so I can keep the airspeed at 55 kts. The airplane doesn't want to slow down and if you are the least bit high, the only option is to lower the nose and pick up speed.
Diving the aircraft in an attempt to lose altitude when flying into a headwind will only increase the required landing distance.
I recently noticed my RV-12iS (about 40 hrs TT) exhibit RPM fluctuations with engine at idle (app. 2,000 RPM)
This happens during descent with throttle at idle or taxiing back to the hangar after the flight.
The RPMs will fluctuate in a consistent and regular cycle from 1,900 to 2,100. It will climb to 2,100, drop to 1,900 and then continually repeat.
Is this normal?
