Important InformationTo get the best out of your new spinner you must make sure that your propeller is balanced. The best way to do this is to have your spinner, propeller and engine dynamically balanced once a year. This balances the spinner, prop and crank with the engine running at cruise RPM. You will be very surprised as to how smooth your power plant will become
