Make sure the shut down levers are fully seated by the springs. Yes, that happened to me. The booster spring on our port engine would drag the throttle back so I loosened that up also.

Re: 671tib lost rpms
Improvement after changing secondaries, one air filter seems to be full of oil as I took them off to clean and one keeps dripping oil anyone know what this could be?

Re: 671tib lost rpms
In general.... if the filter is full of oil and the turbo spins freely.... meaning no oil/grease breakdown from bearing, etc.... it could simply be in need of cleaning if it hasn't been done for a while.... You have Walker Air Seps... or somehting else? If Walker Air Seps…. then you actually put oil on those filters to make them more efficient at air filtration...
