Yesterday I experienced what I though was SAG. I have 106 hrs. on my first set of plugs so I have been expecting it. Had normal RPM on take off roll (4600+) but just crossing the departure threshold it slowly sagged to 4400 (when it should have increased to 4800), then continued to dip down to 3800. I forgot to look at the fuel flow and fuel pressure, but I did note that increasing the mixture improved the issue. I continued around the pattern for an uneventful landing, my passenger never detected that there was a problem and just took my word that "something was not right." I changed out the spark plugs which were moderately well worn - more than half of the central electrode was worn away. I also changed the fuel filter (earls). Upon cleaning the element there was a little bit of fine grit. I probably picked this up in Mexico either in the gas I bought, or just being in the dusty and dirty conditions. On the other hand, SAG may have been accelerated by the use of 100LL on the Mexico trip. Either way, the problem is fixed and power is back to slightly better than it was. My feeling is that is was a clogged fuel filter. The earl's is of good quality and easy to clean, but it is too small and seems to easily clogged with a small amount of contaminant. I will definitely keep my spare one with me in my emergency kit, but I am going to start looking for another larger one that won't be too hard to install.
