The engine/airframe had only 228 hours and now I have 265 hours on it. I had an interesting problem develop this morning. On takeoff and climb out, around 0708 hours, I heard an RPM drop sound with no real indication on the RPM gauge. I leveled the aircraft and reduced throttle to cruise and I looked at the EGT (Exhaust Gas Temp) gauge and notice the number 2 cylinder temp climbing through 1000 degrees with both CHT (Cylinder Head Temp) indicators running about 10-20 degrees higher than normal. I immediately and turned down wind for landing. Landed with no problem just a shallow approach due to I was not at my normal pattern altitude. I taxied back to runway 34 and decided to try it again to see if I could duplicate the problem. Sure enough, just as I rotated for take off, same RPM drop, so I just throttle back, settled the aircraft back to the runway, and taxied back to the hangar. Everything with engine just didn't feel right so I aborted the flight. WhenI was planning on flying to work today for the first time. Bummer. I planned on tearing down and decarbing the engine this fall but I guess I might be doing it early. I am familiar with 2 cylinders/2 cycles but this is the first time in a long that my behind is strapped to one. Any ideas on what I should do and be looking for? Pull plugs and exhaust manifold to check for built up carbon and scored pistons?

Check everything on your engine and airframe : - Read the owner and maintenance manuals (downloadable online) - Fuel : quantity, quality, age, absence of contamination, lines for obstructions, kinks or leaks, vents, cleanliness, pump, condition of carbs and throttle freeness, etc. - Oil : quantity and quality, mixing, age, etc... - Mechanical condition : leaks, cleanliness, integrity, absence of abnormal friction, bolt and head torquing, exhaust, compression, etc... - Cooling : condition of baffling/fans, cleanliness, adequate airflow to fins or radiator, coolant quality and quantity, etc... - Instruments : integrity, accuracy, etc... - Ignition : integrity, wire runs, cleanliness, fit of plug caps, age of plugs. Pull the plugs, do not mix them. Examine them for diagnostic. Verify presence of spark and correct timing. Report any discrepancy.
