For all my piper fellows. A year ago I bought a 1979 Archer II, did pre buy inspection and everything seemed ok. One time on take off I took a look at the RPM gauge and noticed the it was marking at around 2300RPM, I got a little worried thinking it should read at least 2500RPM full open throttle, so I went to my mechanic and explained the RPM reading. He proceeded to check the engine and did a compression check, all in the high 70's. He told me everything seemed ok, so I was ok with that and kept flying it like that. Performance felt very good too in climb and cruise. While in cruise it always wanted to go over to max reading power (past 25ooRPM). Now, a month a couple of weeks ago the plane got out of the annual and everything seemed great, it felt great over all, but again, I glanced at the RPM and in initial roll out it read 2100RPM this time.... As I start to climb it starts to rise little by little and in cruise it reaches high RPM. Compression readings out of the annual are again high 70's. Do you Piper owners have similar readings on take off? Thanks for the feedback.
