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?

RE: engine vibration

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.

RE: engine vibration

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?
