Hi,

the gauge is set to first result in the engine running rough when damaged, and if it is pushed further (i.e. if you don't reduce power) it will finally fail.

Just leave at full power to see whether it will finally fail (should take less than 1-2 minutes at full power between moment of initial running rough and engine failure while in level flight). If it does not ultimately fail, please report back with further information on the circumstances.
