Thank you for contacting Answer Army. The engine manufacturer sets the engines to run at the most efficient level per the models that they are applied too. Husqvarna nor Honda would not recommend any mechanical adjustments because it could possibly void the warranty. The mower does belong to you though, so it is ultimately your decision if you want to carry out any adjustments that will fit your needs.
