My 2 cents
This is what Rotax Rick says on the MZ202.
Quote-O boy. I hate to hear that. The 618 was rebuild able. The case needed welding. We just used all the parts off it for a 670 engine. The MZ 202 has main bearing failure problems. Now they have a 10 hour piston life. The piston pins are falling out. I sold a 503 about 1 1/2 years ago to a guy with the Mosquito. He loves it.

Well, I am not going to flame Rotax Rick because I have never talked or dealt with him....BUTTT!
I had a friend who flies a Kitfox with a grayhead 582 in it. I was his CFI for all of his Sport Pilot training in that airplane. The engine ran perfectly for all the time I had in it with him. He bought it used and it and the engine had 300 or 400 hours on it when he purchased it.
I was a pretty accomplished Rotax 582 guy because I had 100 hours in a Mini-500 with one. The Kitfox NEVER gave one ounce of engine trouble. We tracked oil consumption closely and jetted for 1150-1175 EGT's with almost no carbon buildup.
Now recently, my friend reached 600 hours and sent the engine to Rotax Rick for a rebuild including crankshaft replacement.
Now when it came back, Rick gave my friend instruction on everything that had been done WRONG and the way that engine had been run WRONG for the last 600 TROUBLE FREE HOURS!
He had removed the oil injection system and told my friend he was using the worst oil in the world. He had changed every stupid jet in the engine including even the jet-needle, and he didn't bother sending the ones he removed back!
When my friend installed the rebuilt engine, the jetting was so bad it would barely crank and run.
I formed an pinion from this one situation, that Rotax Rick is a LEGEND IN HIS OWN MIND who either doesn't know what he's doing or he was drunk when he said all the things my friend said he said.
