Do you not have electric cowl flaps? I remember reading about a mod that changes them to manually operated. I’ve not had experience with that, but flap elevator trim interconnect cable is a pretty long push pull and mine was frozen solid. Aircraft spruce sells that type cable by the foot. apparently you can soak in oil and hope to free up. But I just swapped it out with new.
