Hi John,
| Quote: | 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.

When one experiences an in-flight engine problem, it is wiser to land as
soon as possible, and not take-off again before the trouble is sorted out.
| Quote: | 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?
Do not take off again until you've found the cause.

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.
Best of luck,
Regards,
