Howdy
I am new to this list since I have purchased a used Hytek Hurricane UL with a Rotax 447 about 3 months ago. 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?

Thanks in advance
