I have an IO-360, parallel valve, 550 hours SMOH. WW 74 RV prop (250 hours SMOH) with a Jihostrov governor 400 SN. Symptoms, I get a noticeable RPM drop only on climb out. Climbing steady at 2600 RPM (max set for plane) and get an occasional drop in RPM of 50 or so. Just enough to get your attention. If I pull RPM back to 2500 or so it seems to stop. Cruise flight at 2350-2400 no issues.
Have downloaded the Dynon logs to Savvy and looked closely at MAP, oil and fuel pressures, fuel flow, EGT?s and everything else I can think of and no other fluctuations except the RPM. Been happening over the last several months.
Anything else I should check??
