What RPM should a Husqvarna 555 RXT Strimmer be tuned to at full throttle?

Thank you adw.  Is the reverse situation also true? What I mean is if the engine is tuned per your method above, can worn short strings then cause the the rpms to rise, overheating and potentially lead to lean engine damage? Or does this tuning method allow for enough margin for this to happen safely?

 

As an explanation, I use a Oregon jet fit head rather than a bump feed, where the temptation is to keep going with shorter strings rather than change them. I'm not looking for max power output just a safe tune where the engine is fine even if the strings snap off. Thanks

The governed ignition unit will then take care of any over speeding.

Ideal, thank you.  I'll check the tuning as per your method and leave it at that.
