Hey gang me again. Just wanted to run some stuff by y’all. I have a piper archer ii and I had noticed I was only making 2200 rpm static when going full power. Poh says that should be 2325. This is with a standard prop which I have. I’ve also noticed that the number 2 egt runs about 90-100 hotter than the others. Cht is pretty much dead on with the others.
Also if not is in the pattern when I increase from a very low power setting I will get a very suttle hiccup and then the power comes back up. Lastly I get no rpm rise on a shutdown with the mixture. Mag checks are good and cruise speeds suggest that the engine is making good power.
Also I checked the rpm with an optical tach and it is actually getting about 2250 static. Looks like my mechanical tach is off 40-50 rpms
