Default engine vibration

I have the 30cc aw extra 300 with a dle 30. I am getting a lot of vibration at low speed. Mid range and wide open seem fine but at idle its bad. Any suggestions? Thanks a lot

Have you balanced your prop?

Did you balance the prop hub? Spinner? Are you doing test runs with the wings off?

How is it running at idle? A rich low end can cause the motor to vibrate more. Balancing the spinner and the hub of the prop will also help.

Thanks mark sounds like it may be rich on low end. Runs great though with good transition. Also the spinner I got was an aeroworks. Those are balanced when you get them right?
